Replaceable sensor modules for gas detectors, WPDS combustible series

The CAX sensor modules with catalytic sensor offer a high degree of selectivity to interfering agents and are equipped with a permanent memory in which the production parameters are inserted: type of gas, calibration concentration, production date, serial number, etc.

The detector also uses the memory of the CAX module to record the sensor operating hours. The CAX modules guaranteeing a 5-year life allow to extend the life of the detectors of the WPDS combustible series, from 5 to 15 years by replacing the module twice.
