Wall mounted infrared CO2 gas detector with 4-20mA output

    CO2 gas detector, fixed gas detector, infrared CO2 gas detector, gas detector supplier 

    Model CRH-80 is fixed gas detector for CO2 gas detection. It is a new type gas detector which used imported high quality gas sensor and advanced microcontroller technology. Original imported NDIR infrared sensor has good repeatability, long working life and fast response. The cast aluminum material body is explosion proof and stable. Stainless steel sensor cover improved the protection.

    CO2 gas detector features:

    1) High sensibility, rapid response, good linearity and short polarization period;

    2) Two contact relay output can control optional equipment directly;

    3) Explosion-proof design complies with the requirement of applying in Zone 1,2;

    4) Cast aluminum body, solid and durable;

    5) Standard 4 to 20mA output matches to all control units.
