| CxHx-LD Series |
| CxHx-LF Series |
CxHx-LD SeriesCxHx-LD series are the world’s first combustible sensor modules which can detect low concentration of gases up to 5,000ppm in the air. and the available gases are CH4(Methane) & C2H4(Ethylene) & C3H8(Propane) & C4H10(Butane).
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.
