Principle Introduction:

MIX2004 Combustible Gas Sensor advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When there is methane. The sensor’s conductivity will become higher along with the gas concentration rising. With simple electro circuit, convert change of conductivity to correspond output signal of gas concentration.


High sensitivity to methane
Low power consumption
Long life and low cost
Fast response and recovery


Domestic gas leakage detectors
Portable gas detectors
