CL2-H4 Chlorine Sensor

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

Miniature H-Series chlorine sensor for wearable and personal safety devices.

The CL2-H4 is a miniature 0–20 ppm chlorine sensor in the H-Series format, suited to compact personal safety monitors and other space-constrained portable devices. With sensitivity of −150 to −350 nA/ppm and T90 < 35 s, it delivers fast-acting Cl2 detection with low noise and stable baseline performance. An operating life > 18 months (24-month warranted) supports reliable service in harsh, real-world environments.
