MK101 operate on the catalytic combustion principle, and its two arms of electric bridge consists of a test element and a compensate element. Resistance of the test element reised when meeting the combustible gas, in the same time, the output voltage of the bridge changed, the voltage variable is rised in direct proportion as the gas concentration, the compensate element as a reference, and compensate of temperature and humidity.

It is suitable for domestic and portable gas detectors.
