Combustible gas leaking alarm for domestic or industrial area 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.
Applications :
It is widely used in industrial occasion to detect the concentration of natural gas, LPG, CO and alkanes. It is also used in combustible gas leakage alarm system, combustible gas detector and gas concentration meter and so on. <<

Range:0~1000 ppm
_ Application:Carbon monoxide detector/monitor with LCD /light display in civial area ME2-CO electrochemical sensor detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
Applications :
Widely used in civilian area to detect CO concentration. <<
