Concrete pH

Flat surface electrode design
Fast and easy on-the-spot pH measurements on concrete

Extech Instruments, a major supplier of test and measurement equipment for the industrial marketplace, announces its new PH150-C ExStik Concrete pH Test Kit with everything you need for pH testing. The PH150-C’s flat surface electrode design provides fast and easy on-the-spot pH measurements on concrete, and the kit’s waterproof/dustproof design (IP570) floats in water and protects the meter in wet environments.

Its one metre extension cable with probe guard/weight attached to the flat surface Concrete pH Meter for taking measurements on flat concrete surfaces, and the rust-resistant metal weight helps to keep the electrode in contact with the wet concrete surface. The test kit features a probe guard to protect the electrode. To eliminate guesswork, the test kit’s RENEW indicator tells the user when it is time to replace the electrode and the CAL alert informs the user when it is to recalibrate.

The meter includes a dual display with numerical readout and analog bar graph, and the memory function records and recalls 25 sequentially tagged readings, allowing detection of changes over time. 1, 2 or 3 point calibration automatically recognizes buffer solutions, and the kit features a simultaneous display of pH and temperature with ATC. Furthermore, there is a Data Hold, Auto power off and low battery indicator.

The PH150-C test kit comes complete with a flat surface concrete pH electrode, protective sensor cap, sample cup with cap, plastic stand (that helps keep the meter in place), 1M extension cable with weighted probe guard, plastic bottle, four 3V CR2032 button batteries, a 48” (1.2m) neckstrap, and a carrying case.
