MC105 adopts catalytic combustion principle, and its two arms of electric bridge consists of a test element and a compensate element. The resistance of the test element rises once it meets the combustible gases, in the same time, the output voltage of the bridge changes and the voltage variation rises in direct proportion to the gas concentration. The compensate element, as a conference, has the function of compensating temperature and humidity.


  1. It is widely used in industrial occasion to detect the
    concentration of natural gas, LPG, CO and alkanes.
  2. It is also used in combustible gas leakage alarm system,
    combustible gas detector and gas concentration meter and
    so on.


  1. Bridge output voltage in linear
  2. Fast response
  3. Good repeatability and selectivity
  4. Resist H2S poisoning & organosilicon.
