| CxHx-LF Series |
CxHy-LD-3V SeriesCxHy-LD-3V series are the world’s first combustible sensor modules which can detect low concentration of gases up to 2,000ppm for C2H4(Ethylene) and upto 5,000ppm for CH4(Methane) or C3H8(Propane) or C4H10(Butane) gases in the air.
Its consistent Stability through the life cycle and Temperature change Effect Compensation are incomparably favored by industrial field experts carrying various flammable, explosive, and hazard gases.
