Three in one sensor.

The duct mount EE850 from E+E Elektronik measures CO2 concentration up to 10000 ppm (1 %), as well as relative humidity (RH) and temperature (T). It is ideal for demand controlled ventilation, building automation and also for climate and process control. The 3-in-1 sensor features a dew point temperature (Td) and a passive temperature output.

The EE850 incorporates the E+E dual wavelength NDIR CO2 sensor, which is highly insensitive to pollution. The CO2 autocalibration ensures excellent long-term stability, while the temperature compensation leads to high measurement accuracy over the entire working range from -20 to 60 °C (-4...140 °F). The CO2 sensing cell is located in the innovative device enclosure and thus very well protected.

The combined RH/T sensing element is placed inside the probe. The E+E proprietary coating protects the sensing element from dust and corrosion, which leads to accurate measurement even in harsh environment. It also improves the long-term stability by preventing stray impedances caused by deposits on the active sensor surface.

The CO2, RH, T and Td measured data is available on the analogue outputs. Additionally, the EE850 features a passive T output. Configuration and adjustment can be easily performed with an optional adapter and the free EE-PCS configuration software.

External mounting holes allow for mounting the transmitter with closed cover. This saves time and protects the electronics from construction site pollution. Alternatively, the device can be installed with the mounting flange included in the scope of supply.
