MC105 gas sensor adopts a catalytic combustion principle, and its two arms of electric bridge consist of a test element and a compensating element. The resistance of the test element rises once it meets the combustible gases, at the same time, the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The compensating element, as a conference, has the function of compensating temperature and humidity.
MC105 sensor can detect CH4 and flammable gas sensor for alarming, metering and detecting gases.
