Active Chlorine sensors

[vc_single_image image=”6814″ img_size=”full” alignment=”center”]

Active Chlorine sensors : CAA2527 – 07 – 57 – 45
4-20 mA / 0 … 2 – 10 – 100 – 200 ppm

CAA2507, CAA2527, CAA2557 and CAA2545 sensors are used to measure inorganic active chlorine, ie hypochlorous acid in drinking water, swimming pool water (without chlorine stabilizer), seawater or similar water quality.

Advantages:

Amperometric measurement
Continuous accurate and reliable analysis
Fast execution
