CL2-A1 Chlorine Sensor

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

Portable chlorine sensor for industrial safety and environmental monitoring.

The CL2-A1 is a 0–20 ppm chlorine sensor in the standard A-Series package, ideal for portable and fixed instruments used in industrial hygiene, water treatment and environmental safety. Its high output sensitivity (−350 to −750 nA / ppm) delivers strong signal-to-noise for simple analogue frontends, while fast T90 < 60 s supports rapid alarm decisions. With a 24-month warranted life and robust cross-sensitivity performance, CL2-A1 offers reliable Cl2 monitoring across typical workplace and process environments.
