Carbon dioxide sensor.

Engineered for accuracy, built to endure.

The SCD53 CO₂ sensor, from Sensirion, is designed to address an increasingly relevant challenge in gas sensing: maintaining accuracy long-term without relying on costly manual recalibration or regular exposure to outdoor fresh air. This their next generation high-performance CO₂ sensor is to be launched in late 2026.

Many sensors in use today successfully apply automatic baseline calibration algorithms (i.e., “ABC” or “ASC”) to maintain their accuracy over time. These assume regular exposure of the sensor to air at the atmospheric baseline concentration. However, not all applications can guarantee fulfillment of this condition, including demand-controlled ventilation (DCV) systems for permanently occupied spaces, exclusively mechanically ventilated buildings, or smart greenhouses.

The SCD53 combines Sensirion’s leading expertise in photoacoustic NDIR sensing with advanced laser technology for excellent long-term stability independent of fresh-air based recalibration algorithms. Furthermore, the sensor provides best-in-class accuracy, with robustness against dust, vibrations or mechanical forces. Integrated humidity and temperature compensation, as well as optional pressure correction, enable reliable readings across a demanding range of environmental conditions. On-demand measurements, compact sensor size and a reflow solderable LGA package make integrating SCD53 simple, flexible and cost-efficient.

Carbon Dioxide sensors at Biennale Venezia!

Some of its leading-edge carbon dioxide sensors  have been donated by Vaisala to the team responsible for creating a thought-provoking and inspirational exhibit at this year’s Biennale Architettura in Venice, Italy. One of the key aspirations for the project is to use trees to create an agreeable indoor climate.

Commissioned by the Flanders Architecture Institute and curated by landscape architect Bas Smets, the Belgian Pavilion will this year feature an exhibition titled ‘Building Biospheres’. 

“Climate change and the recent crises that we have faced, are forcing us to rethink the relationship between architecture and nature,” Smets explains. “Historically and traditionally, architecture has isolated itself from the natural world, recreating an indoor climate with heating, ventilation and mechanical tools. As humans we prefer the conditions of a sub-tropical climate, so our project will investigate and demonstrate what happens when sub-tropical plants such as the camphor tree are used to manage the indoor environment.”

With its inception in 1895, La Biennale di Venezia is one of the longest-running cultural festivals in the world, and now features around 30 permanent pavilions established by different countries. In 2025, the goal of the Biennale Architettura will be to eliminate waste, recycle and circulate materials, and regenerate natural systems to demonstrate that the built environment can coexist harmoniously with the natural environment.

In November 2024, a prototype of the ‘Building Biospheres’ exhibit was built at the Faculty of Bioscience Engineering at Ghent University, where Professor Kathy Steppe and her team established a greenhouse facility in which sub-tropical trees are closely monitored with TreeWatch technology. Prior to the beginning of the Biennale Architettura, all of the plants and associated monitoring infrastructure were transported to Venice and re-established within the Belgian Pavilion. Four of the key environmental measurements are light, temperature, humidity and carbon dioxide because these are the factors with greatest influence on indoor human comfort and well-being.

Explaining the potential for utilising plants to manage indoor environments, Prof. Steppe says: “In order to maintain optimal conditions inside buildings, it is usually necessary to implement some form of heating, ventilation and/or air conditioning, but this can be very costly, both financially and from a carbon footprint perspective.” Comparing and contrasting the built and natural environments, she continues, “Plants actively interact with and help regulate their local climate through processes such as photosynthesis and transpiration. This means, for example, that the CO₂ produced by humans, other organisms and natural processes can be taken up by plants during photosynthesis, helping to prevent excessive indoor CO₂ build-up.”

As a greenhouse gas, CO₂ levels in the atmosphere are having an impact on climate change. Indoors, CO₂affects the comfort and performance of the people inside a building. Occupied spaces with good air exchange may contain 450-1,000 ppm CO₂ , but anything above this can induce drowsiness. Levels above 2,000 ppm CO₂ cause headaches, sleepiness, poor concentration, loss of attention, increased heart rate and slight nausea. Exposure to very high levels (from oil/gas burners or gas leaks for example) can even result in fatalities from asphyxiation.

According to the International Energy Agency (IEA), the operations of buildings account for 30% of global final energy consumption and 26% of global energy-related emissions (8% being direct emissions in buildings and 18% indirect emissions from the production of electricity and heat used in buildings). The climate crisis is therefore challenging all sectors, and the building industry in particular, to find ways to lower greenhouse gas emissions. ‘Building Biospheres’ therefore seeks to investigate the opportunities presented by the integration of plants into indoor environmental management, and to engage with the architecture and building design community, to challenge traditional approaches to building design and operation.

The ‘Building Biospheres’ exhibit will serve as a living laboratory, exploring the ways in which plants can be used to complement traditional energy-intensive building management technologies. Vaisala’s CO₂ sensors have therefore been deployed at different locations throughout the exhibit: one outdoors, one in the entrance hall of the pavilion and one within the plant canopy in the ‘Building Biospheres’ room, to monitor how effectively the plants help regulate indoor CO₂levels.

This year, visitors to the Belgian Pavilion of the Biennale Architettura will be able to view live data from the ‘Building Biospheres’ exhibit. “This is one of the most prestigious architectural events in the world,” Prof. Steppe adds. “So, it represents a fantastic opportunity to inspire building designers from around the globe. The most obvious applications – you could call them the lowest hanging fruit! – are large buildings such as train stations and airports.”

The objectives of the Biennale Architettura 2025 align with Vaisala’s sustainability objectives, including the company’s core purpose, which it describes as: taking every measure for the planet. “We were delighted to be invited to participate in this highly respected event,” comments Vaisala’s Pekka Ravila, Vice President, Industrial Measurements EMEA. “Not just because it highlights the performance of our CO₂sensors, but mostly because this represents a very exciting opportunity to help create a paradigm shift in the way that buildings are designed and managed. If we can achieve that, the potential beneficial impacts on climate change will be enormous.”

Summarising, Prof. Steppe says: "If we are to convince building designers to incorporate plants into their design, it is essential that we are able to supply them with data to support our ideas. Vaisala’s carbon dioxide sensors are therefore playing a vital role in helping us to demonstrate how plants are able to help regulate indoor CO₂levels naturally, without the need for a heavy carbon footprint, and with the added benefit that the plants look great!”

Keeping an eye on the volcano!

Following the eruption of the Cumbre Vieja volcano in La Palma in 2021, the National Geographic Institute (Instituto Geográfico Nacional - IGN) has strengthened its system for monitoring volcanic activity on the island with a new gas detection tool.

The FLIR G343 OGI camera, supplied by Apliter Termografía, can identify carbon dioxide (CO₂) emissions in real time with high accuracy, improving risk assessment capabilities in areas affected by volcanic activity.

The challenge of gas detection in La Palma.
Volcanic activity in La Palma has created a complex situation for environmental surveillance and safety. Although the eruptive phase of the Cumbre Vieja volcano finished at the end of 2021, the emission of gases, such as CO₂, remains a challenge. Since it is a colourless and odourless gas, it can build up in areas that are difficult to access. This creates risks for both the population and the research teams working on the island. The accumulation of CO₂ in low or poorly-ventilated areas displaces oxygen from the air. This can cause dizziness, shortness of breath, disorientation and even loss of consciousness. In volcanic environments, where gas is concentrated in depressions in the ground or enclosed spaces, the risk is even higher.

Deputy Director of IGN & Commercial Director
of Apliter with the FLIR G343

In La Palma, the lack of real-time sensors made it difficult to detect these dangerous areas, which increased the risk of accidental exposure. To improve the surveillance and monitoring of these emissions, IGN needed a solution, such as an OGI thermal imaging camera, that would provide accurate data immediately and enable rapid action.

To address this challenge, Apliter Termografía supplied the FLIR G343, a specialised gas detection device using Optical Gas Imaging (OGI). Unlike traditional methods, which require sample collection and laboratory analysis, this thermal imaging camera can detect gases directly in the field. It provides real-time data that optimises monitoring and reduces exposure to risk areas.

Innovation in volcano monitoring.
Carmen López, the Deputy Director General of Surveillance, Alerts and Geophysical Studies at the National Geophysical Observatory - IGN, highlighted the importance of this new tool, stating that “No volcano observatory has a volcano surveillance tool as powerful as this camera”.

Detection of gas  using the OGI camera.

Apliter Termografía’s commercial director travelled in person to La Palma to deliver the FLIR G343 and demonstrate how it works. During the field tests, IGN researchers saw first-hand how the device can identify areas with a build-up of CO₂, optimise their everyday tasks and improve safety in post-eruption monitoring.

Impact of the thermal imaging camera with optical gas imaging (OGI) on safety and science.
By adopting the FLIR G343, IGN has managed to optimise its ability to respond to post-eruption activity in La Palma. The thermal imaging gas detection camera has not only enhanced researchers’ safety, but also aids real-time decision-making and collection of essential data for scientific studies on the evolution of the phenomenon and its long-term implications.

This success story shows how a combination of advanced technology and specialised knowledge can make a big difference in natural risk management. The collaboration between Apliter Termografía and FLIR reaffirms their commitment to safety, research and development of innovative solutions for high-risk environments.

Easing pressure and improving efficiency in Datacentres.

Anu Kätkä an expert in environmental monitoring and control from Vaisala, explains how Datacentre companies can respond to external pressures by utilizing the latest measurement technologies to optimize both energy efficiency and operational uptime.

The datacentre sector is experiencing unprecedented pressure from a number of directions. Customers are demanding the highest levels of performance and sustainability, alongside financial, environmental and political pressure to improve energy efficiency. At the same time, recent growth in the demand for Datacentres is set to accelerate further with increasing investment in AI infrastructure, and growing concern about a lack of capacity in AI-ready Datacentres.

Reducing CO₂ emissions through sensor selection.

Datacentres account for at least 1% of global electricity consumption, so notwithstanding escalating energy costs, and in the context of climate change, it is essential that Datacentres are able to optimize their energy efficiency and reduce CO₂ emissions.

Up to 40% of energy consumption in Datacentres is used for cooling and air conditioning. So, reduction in energy use for these purposes will help to improve energy efficiency. However, the performance of computers and servers in Datacentres can be adversely affected if there is insufficient cooling – overheating can cause IT equipment to fail, resulting in significant and costly downtime. A fine balance therefore exists between minimising the energy consumption of cooling operations and maximising the uptime of IT equipment. This is why accurate, reliable sensors play such an important role.

The control of HVAC systems can only be as accurate and precise as the sensors upon which they depend. If the measurements are inaccurate, the output of the building management system (BMS) controller will also be inaccurate. If a poor-quality sensor gives an incorrectly high temperature reading, the controller will react by over cooling and thereby increasing energy costs and emissions. If the same sensor gives an incorrectly low reading, cooling will be insufficient, which can lead to IT equipment working inefficiently or even breaking down.

Measurement stability is key to long-term performance.
It is important to remember that measurement precision is not just about accuracy at the time of installation. All sensors drift over time, to a greater or lesser degree, so measurement stability is vitally important. Some sensor suppliers claim very high accuracy, but they may not have high stability, which means that measurements from these sensors will damage energy efficiency, even after a short period. Good-quality sensors provide accurate measurements that remain accurate in the long term. By ensuring the controller has accurate inputs it is possible to precisely control indoor conditions and optimize energy efficiency.

Highlighting the importance of sensor accuracy, Vaisala participated in a simulation based on three real Datacentres in Europe, and found that a setpoint temperature difference of just 1°C (resulting from imprecise sensors) could increase annual energy usage by as much as 8.5%.

An important point to note here, is that the cost of high-quality sensors is insignificant (and almost non-existent) in comparison with both the energy efficiency that they enable and with the value of the IT assets that they help protect.

Take advantage of weather forecasts.
By anticipating upcoming hot weather, Datacentres can use predictive cooling to avoid early chiller startup, make optimal use of free cooling, and reduce chiller operating hours. This proactive approach translates into further energy savings and a lower carbon footprint.

Change sensors to reduce greenhouse gas emissions and cabling.
Typically, the internal environments of Datacentres are monitored by hundreds or even thousands of sensors, and each instrument needs a connection with the BMS controller so that it can report the measurement values. Sensors with analog signals require a dedicated cable from each sensor to the controller. However, if operators can switch to a fieldbus connection it becomes possible to daisy-chain the instruments so that only one cable is needed, and thereby dramatically reduce the cabling requirement. For example, a 100-meter aisle with 30 instruments, each with dedicated cables spaced three meters apart, with a three-meter cable drop, would require 1695 meters of cable weighing 110 kg. However, in stark contrast, a fieldbus communication protocol would allow sensors to be daisy-chained, requiring just 187 meters of cable, weighing just 12 kg. That amounts to 89% less cabling, which leads to more efficient power distribution and lower energy losses; reducing energy consumption and lowering CO₂ emissions.

How to choose a sensor provider.
Most reputable businesses are looking to lower their greenhouse gas emissions – in their own processes, in the use of their products, and in their supply chains. Consequently, when choosing sensors, it makes sense to look for a provider with a sustainability focus. For example, Vaisala's instruments are produced using renewable electricity and the company has set science-based targets for reducing emissions. In 2024 Vaisala received a gold medal from EcoVadis for its sustainability management system, and Vaisala has been ranked 38th in the 2025 edition of the World’s Best Companies – Sustainable Growth ranking by TIME Magazine and Statista.

The challenge: uptime is non-negotiable.
Both temperature and humidity levels must be very carefully maintained to achieve the uptime requirements of large Datacentres. However, larger data halls can be more challenging to monitor because they have a greater potential for temperature variation - meaning it's important that there are sufficient numbers of temperature sensors to ensure that all servers are monitored. In addition to the temperature issues discussed above, IT equipment is also adversely affected by humidity. Low levels increase the risk of static electricity, while high levels of humidity can result in condensation, both of which can damage delicate equipment. Datacentres often have no maintenance workers onsite, so equipment reliability is crucial.

With Vaisala equipment currently operating on the planet Mars, the long-term reliability of Vaisala sensors in remote locations is beyond question. In addition, Vaisala has developed portable reference probes so that Datacentre maintenance staff can perform a quick calibration check on installed sensors. Vaisala equipment does not therefore need to be sent offsite for calibration, and service staff do not need to bring large amounts of equipment onsite – a useful feature for remote locations.

Summary.
Accurate, stable sensors, weather forecast utilization, daisy chaining with fieldbus connectivity, and sustainability-focused supply chains all contribute to operational reliability and therefore uptime, whilst also minimizing CO₂ emissions. Furthermore, Vaisala is a global leader in measurement instruments, with unsurpassed sustainability credentials, defining its core purpose as: taking every measure for the planet.

Sustainable Sensor People!

Leuze, "The Sensor People," has achieved the goals for 2022 to become a CO₂ -neutral company in Germany thanks to improved energy efficiency. Indirect emissions in the supply chain will also be examined going forward. Environment Social Governance (ESG) is part of the company strategy. "Growth means taking responsibility - for the environment and society, too." In this context, they have achieved an initial goal that they were aiming for and the company is CO₂ neutral in Germany since 2022.

Improved energy efficiency.
As part of their growth strategy, Leuze had set the target to become CO₂  neutral in Germany by the end of 2022. To do so, the company first examined its direct emissions and on this basis, it optimized the issues that were identified: thanks to comprehensive investment in new buildings and the modernization of existing buildings, it was possible to achieve a substantial reduction in energy consumption. Leuze was also able to significantly improve its energy efficiency in production: this was due to a massive expansion of its own renewable energy generation using photovoltaics, among other measures. As a result, The Sensor People were able to reduce last year the purchase of electricity from external sources by about half. Leuze has been using 100% green electricity by external electricity for years. Some of this is supplied by Leuze's own, leased hydroelectric power stations. The vehicle fleet has also been optimized: hybrids and fully electric company cars are already in use. And more will follow. In addition, Leuze provides charging stations to its customers and employees. The company also offers its employees "Job-Rad" (bicycle to work), and opportunity to charge e-bike batteries at the company.

Small regional projects can also contribute to climate protection: with the Leuze SenseBees colonies, Leuze supports the local ecosystem at the headquarters of the company in Owen (D).

Preventing deforestation.
In order to avoid direct CO₂ emissions, Leuze supports an international forest protection project in northern Brazil on approx. 148,000 hectares. This is not related to reforestation but is a project that supports the preserve the rainforest as a natural CO₂ store. The forest protection project saves emissions by avoiding the deforestation of the jungle.

Sustainability remains firmly on the agenda.

For Leuze, it is not enough to avoid direct emissions. As an international company, The Sensor People also want to make a contribution to more sustainable management worldwide. Therefore, it also includes checking the indirect mission in the supply chain. With most companies, these make up a large part and are more difficult to implement. In this context, the question arises: where do the components come from? How and in what conditions are they manufactured? Do these reflect Leuze’s ethical and ecological ideas? What does this mean in terms of competition? In order to get answers and initiate improvements, Leuze carries out regular audits, not only in Germany but also in manufacturing countries such as Asia.

For a circular economy.
Further, Leuze also plans to become CO₂ neutral on the product side. For this purpose, individual new sensor series are already being considered in the sense of the "cradle to cradle" approach. In this context, The Sensor People check to what extent a specific product contributes to CO₂ emissions and what this means for system operators with Leuze sensors.

Innovation in vacuum recognised.

The company Climeworks has been awarded with the Innovation Award by Busch Vacuum Solutions for its advanced use of vacuum technology. Climeworks is the first company to use Direct Air Capture technology to remove carbon dioxide from the atmosphere. In this way, the company is actively making an important contribution to reducing global warming.

Climeworks and Busch have a close partnership from the beginning. Climeworks has now been awarded the "Innovation in Vacuum Busch Award 2021" for its innovative use of vacuum technology in CO₂ removal. Managing Director and founder of Climeworks Jan Wurzbacher accepted the award together with other representatives of the company during a small ceremony at the headquarters of Busch Vacuum Solutions in Maulburg (D).

In these unique plants, MINK claw vacuum technology from Busch is used to filter CO₂. Busch presents the "Innovation in Vacuum Busch Award" once a year. This award honors individuals or companies that make use of vacuum technology with particularly innovative ideas and thereby serve the well-being of people and the environment. The "Innovation in Vacuum Busch Award" was first presented in 2013 on the occasion of the 50th anniversary of Busch Vacuum Solutions.

The rise in temperature caused by climate change can only be limited by restoring a healthy balance in the CO₂ content of the atmosphere. This can only be realized if both current emissions are drastically reduced and unavoidable emissions that have already been emitted are removed from the air.

Using Climeworks' Direct Air Capture technology, CO₂ is filtered directly from the air. CO₂ collectors selectively capture carbon dioxide in a two-step process. First, air is drawn into the collector by a fan. The carbon dioxide is captured on the surface of a highly selective filter material located inside the collectors. After the filter material is filled with carbon dioxide, the collector is closed, and the temperature is raised to 80 to 100 °C - releasing and capturing the pure carbon dioxide. The filtered CO₂ is extracted using MINK claw vacuum pumps from Busch.

It is then mixed with water and injected underground into basalt rock by Climeworks' partner Carbfix. Over a period of a few years, the CO₂ mineralizes itself and is thus permanently and safely removed from the atmosphere and converted back into rock underground. Climeworks' technology is powered exclusively by renewable energy or waste heat, and the modular collectors can be combined to create systems of various sizes.

Miniaturized CO₂ sensor.

Sensirion has launched a new product in its SCD4x miniaturized CO₂ sensor series. The SCD42 has been designed for products that fall under California’s Building Energy Efficiency Standards (Title 24), and is therefore perfectly suited for US HVAC applications.

“Smart building ventilation systems leverage a CO₂ sensor to optimize indoor air quality while keeping energy consumption at a minimum. Thanks to its compact size and easy assembly, the SCD42 lowers the hurdle for integrating a CO₂ sensor into ventilation systems. I am excited that the SCD42 will help boost people’s well-being and reduce our buildings’ carbon footprint,” says Marco Gysel, CO₂ Sensors Product Manager at Sensirion.
 

High levels of carbon dioxide (CO₂) compromise humans’ cognitive performance and well-being. Thanks to new energy standards and better insulation, houses have become increasingly energy efficient. However, CO₂ produced by human metabolism can accumulate rapidly indoors. Therefore, CO₂ is a key indicator for indoor air quality. Measuring indoor CO₂ concentration enables smart ventilation systems to regulate ventilation in the most energy-efficient and people-friendly way. Moreover, indoor air quality monitors and other connected devices can help to maintain a low CO₂ concentration for a healthy, productive environment.

SCD4x Gadget

The SCD42 is Sensirion’s newest addition to the SCD4x product line.

The Amager Bakke Waste-to-Energy Plant is one of the largest CHP plants in northern Europe, with the capacity to treat 560,000 tonnes of waste annually. Developed by the Copenhagen-based waste management company ARC (Amager Ressourcecenter), which is jointly owned by five Copenhagen-area municipalities, the CHP plant features a number of innovations including a rooftop artificial ski slope, which is part of an outdoor activity centre known as CopenHill.

Carbon capture pilot plant

The owners of the Amager Bakke plant are planning to apply for 1.5 billion DKK ($230 million USD) for a CCS plant capable of capturing 500,000 tonnes of CO₂ per year – if the right regulatory framework and sufficient funding is provided by the Danish state. This plant would employ the same amine scrubbing process that has been proven by the pilot carbon capture plant.

A case study, Decarbonization technology proven at Waste-to-Energy Plant has been published and shows that the project is utilising advanced gas analysers from Vaisala (FIN) to measure carbon capture efficiency and therefore CCUS viability. These analysers are unique because they operate inline an in real-time.

Miniaturized CO2 sensor.

Sensirion has launched a new product in its SCD4x miniaturized CO2 sensor series. The SCD42 has been designed for products that fall under California's Building Energy Efficiency Standards (Title 24), and is therefore perfectly suited for US HVAC applications. The sensor is now available worldwide through their distribution network.

"Smart building ventilation systems leverage a CO2 sensor to optimize indoor air quality while keeping energy consumption at a minimum. Thanks to its compact size and easy assembly, the SCD42 lowers the hurdle for integrating a CO2 sensor into ventilation systems. I am excited that the SCD42 will help boost people's well-being and reduce our buildings' carbon footprint," says Marco Gysel, CO2 Sensors Product Manager at Sensirion.

High levels of carbon dioxide (CO2) compromise humans' cognitive performance and well-being. Thanks to new energy standards and better insulation, houses have become increasingly energy efficient. However, CO2 produced by human metabolism can accumulate rapidly indoors. Therefore, CO2 is a key indicator for indoor air quality. Measuring indoor CO2 concentration enables smart ventilation systems to regulate ventilation in the most energy-efficient and people-friendly way. Moreover, indoor air quality monitors and other connected devices can help to maintain a low CO2 concentration for a healthy, productive environment.

The SCD42 is Sensirion's newest addition to the SCD4x product line. Specifically designed for products that fall under California's Building Energy Efficiency Standards (Title 24), the SCD42 offers unmatched cost effectiveness for the US HVAC market. This disruptive innovation is based on the principle of photoacoustic sensing and combines minimum size with maximum performance to open up numerous new possibilities for integration and application. The SCD42 offers an accuracy of ±75 ppm at 400-1000 ppm. SMD compatibility and its small footprint allow cost-effective and space-saving integration to increase device manufacturer's freedom of design. This integrated, best-in-class humidity and temperature sensor enables superior on-chip signal compensation and additional RH and T outputs. Finally, the large supply voltage range (2.4-5.5 V) and the robust resistance to external stresses make the SCD42 the perfect fit for all kinds of customer needs.

Gas meter modules for a sustainable future.

Multi-gas meter modules measure pure hydrogen, hydrogen blends and natural gas

The Sensirion SGM64xx is the first gas metering module on the market able to measure any gas mixtures, including pure hydrogen, blends of hydrogen, biomethane and natural gas types H, L, and E. Therefore, no meter replacement nor any firmware update will be required for meters that feature the SGM64xx product line when natural gas is gradually or fully substituted with hydrogen. Since replacing even a small fraction of meters currently in use is significantly more expensive than installing multi-gas capable meters today, utility companies can rest easy and cut future costs significantly.

Proven technology for years
Thermal-mass technology has been proven over the years by more than six million meters in the field and billions of hours of reliable metering. Two third-party studies confirm the long-term reliability of this technology for applications in extreme environments. These studies investigated gas meters that were in the field for more than a decade. All meters operated well within the accuracy limits set for field operation, and most of them met the requirements placed on brand-new gas meters. In addition, Sensirion’s gas meter modules are certified according to the EN 14236 and OIML R 137 standards, with EN 17526 certification on its way. These evaluation certificates facilitate MID approval for gas meter manufacturers.

Carbon neutrality, sustainability and the reduction of CO2 emissions are the main global trends in the energy sector. Our current gas infrastructure must be prepared for the arrival of renewable gases. In one example, starting in 2025, all new gas boilers installed in Britain will have to be compatible with pure hydrogen. Similar requirements for gas meters are expected to follow shortly after. These meters will be ready for whatever the future holds.

The SGM64xx is based on the proven and reliable SGM63xx platform, and brings it to a new level by extending its measurement capabilities to pure hydrogen. This is achieved via an augmented calibration procedure, which otherwise does not introduce any changes to the product’s mechanical, electrical and software interfaces. Furthermore, the hydrogen flow ranges supported by SGM64xx are three-times higher than those of natural gas, which guarantees a compact meter size no matter the hydrogen content.

Gas meters incorporating thermal-mass modules are the best choice for the transition towards a sustainable future. Sensirion’s gas meter modules provide excellent measurement performance and robustness at ultra-low power consumption levels. Therefore, they are suitable for residential and industrial applications covering flow ranges from G1.6 to G25.

Attaching any Indigo-compatible measurement probe to the Indigo510 transmitter is easy and convenient. “With the Indigo510 our customers can measure humidity, dew point, moisture in oil, temperature, carbon dioxide, and vaporized hydrogen peroxide with the assurance of reliability, accuracy, and the strong chain of data provided by the Indigo ecosystem. The new transmitter provides the quality and performance that Vaisala is renowned for in a more affordable, but equally robust package,” Lehto concludes.

The  transmitter extends the options for data visualization, connectivity, supply voltage, and wiring compared to using a stand-alone probe. In addition, customers benefit from regular platform and software updates.

A smart choice for industrial customers
Vaisala’s unique and growing Indigo product family ensures stable and reliable measurements in diverse industrial applications and environments.

The Indigo family forms a modular ecosystem with interchangeable smart probes, robust transmitters, and intuitive Vaisala Insight PC software. The probes can be used independently without a transmitter, or together with the Indigo500 or Indigo200 series transmitters to extend their features. The modular plug-and-play design makes the Indigo probes and transmitters easy to install, use, and maintain.

Simpler incubator monitoring.

Vaisala has announced their easy-to-install wireless carbon dioxide measurement solution to simplify incubator monitoring and enable cost savings for customers. Deliveries will commence next month (July 2021)

This new life science environmental measurement solution combines Vaisala’s carbon dioxide probe GMP251 with Vaisala wireless RFL100 data logger. The new configuration leverages the superior measurement stability and accuracy of the GMP251 probe, and provides reliable carbon dioxide percentage measurements for incubators used for example in cell culturing, gene therapy, and vaccine research.

“Traditional carbon dioxide measurement installations take up a lot of space and can be complicated to install and maintain, not to mention the related cost,” says Product Manager Anniina Uotila of Industrial Measurements, Vaisala. “The RFL100’s CO₂ configuration enables a much simpler, wireless setup that is ideal for incubators in both strictly regulated GxP and less regulated non-GxP applications. Wireless data loggers also eliminate the need for expensive Ethernet connectivity for each data logger. Additionally, our incubator customers can benefit from the RFL100’s local display of carbon dioxide data next to their assets.”

The RFL100 can provide several measurements in a single data logger: CO₂ percentage, temperature, and humidity. Along with the GMP251 carbon dioxide probe, other RFL100 compatible probes include Vaisala’s TMP115 temperature probe, and the HMP115 and HMP110 temperature and relative humidity probes.

All RFL100 data loggers connect to Vaisala’s viewLinc software for monitoring, alarms, and reporting. RFL100-series loggers operate on Vaisala’s proprietary LoRa® based VaiNet wireless radio technology with a signal reach of over 100 meters, even in complex, obstructed indoor environments. VaiNet uses LoRa® modulation that prevents signal interference with WLAN applications. To ensure data integrity, all VaiNet data transmissions are encrypted and verified before being stored in viewLinc’s secure database.

Vaisala RFL100 data loggers use an external power supply for carbon dioxide measurement and include a lithium battery backup to secure data logger memory during power or network interruptions.

"Our customers appreciate VaiNet’s secure wireless connectivity and ease of deployment. Installing Ethernet access for each individual data logger is unnecessary when you have a reliable signal with significant reach, like the RFL100,” Uotila says. “Combined with the GMP251 probes, which provide a wide operating temperature range and high accuracy, the RFL100 data loggers also make probe calibration information available in the viewLinc monitoring system.”

In addition to data integrity and global compliance, Vaisala’s award-winning viewLinc Continuous Monitoring System provides user-friendly software, web-based user access, real-time data, and remote alarm capabilities.
