Winsen MC119 Catalytic Flammable Gas Sensor

Winsen Electronics, MC119 adopts catalytic combustion principle, and detects hydrogen, ethylene, gasoline, VOC such as alcohol, ketone, benzene.
MC119 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.

Features:

It has good sensitivity to methane in wide range, and has advantages such as long lifespan, low cost and
simple drive circuit &etc. The bridge output is linear, quick response, good repeatability and selectivity,
good stability, excellent resistance to the interference of H2S
gas and organosilicone
