HCL-B1 Hydrogen Chloride Sensor

HCl Gas Sensor, Electrochemical, B-Series, 0–100 ppm range
Hydrogen chloride gas sensor for fixed and high-humidity industrial applications

The HCL-B1 is a 0–100 ppm hydrogen chloride sensor in the B-Series format, optimised for fixed gas detection in semiconductor fabs, stack emissions, process control and high-humidity industrial environments. With 120–250 nA / ppm sensitivity at 25 ppm HCl and T90 < 200 s, it combines strong signal output with robust stability. Cross-sensitivities are well characterised, and the sensor carries a 12-month warranty; operating life depends on application conditions.
