Catalytic Combustion Gas Sensor
Application:
Concentration detection of natural gas, liquefied gas, coal gas, alkane class and other combustible gases, combustible gas leakage alarm, combustible gas detector, gas concentration meterProduct characteristics:
Good stability1. Description
ZC 25 / ZC 25 C catalytic combustion gas sensor work according to the principle of catalytic combustion effect, by the detection element and compensation element pair of a bridge, arm, when the combustible gas detection element resistance increases, bridge output voltage, change, the voltage variable with the gas concentration, compensation element for the reference and temperature and humidity compensation effect
