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.
It is widely used in industrial occasion to detect the concentration of hydrogen,ethyne, gasoline,VOC such as alcohol,ketone,benzene.
