CL2-B1 Chlorine Sensor

Cl2 Gas Sensor, Electrochemical, B-Series, 0–20 ppm range

Robust chlorine sensor for fixed installations and high-humidity environments.

The CL2-B1 is a 0–20 ppm chlorine sensor in the larger B-Series package, optimised for fixed gas detection and high-humidity applications such as scrubber monitoring, water treatment plants and industrial ventilation systems. Its high sensitivity (−600 to −1150 nA / ppm) supports long cable runs and low-noise analogue transmitters, while the increased electrolyte volume improves stability under varying environmental conditions. A 24-month warranted life helps OEMs minimise maintenance in demanding installations.
