CL2-D4 Chlorine Sensor

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

Miniature chlorine sensor for clip-on and compact portable instruments.

The CL2-D4 is a miniature 0–20 ppm chlorine sensor designed for slim, lightweight portable and clip-on personal monitors. Its D-Series format reduces footprint and mass while maintaining reliable Cl2 response for confined-space entry, water treatment and industrial hygiene. With T90 < 35 s and a typical operating life > 18 months (24-month warranted), CL2-D4 balances fast response with robust field performance in challenging environments.
