Catalytic Combustion Gas Sensor

ZC25B Catalytic Combustion Gas Sensor

for industry gas monitoring

Application:

It can be used to test the concentration of natural gas in domestic and industrial sites. It can also be applied to combustible gas leakage alarm, combustible gas detector, gas concentration meter.

Product characteristics:

Good stability
Quick response
The bridge output is linear
Good repeatability and selectivity
Excellent resistance to the interference of H2S gas and organosilicone 

1. Description

ZC25B catalytic combustion type gas sensor works according to the principle of catalytic combustion effect, by the detection element and compensation element pairing constitute a bridge arm, in the combustible gas detection element resistance increases, the bridge output voltage changes, the voltage variable increases with the increase of gas concentration and proportional to the compensation element reference and temperature and humidity compensation.
