N-CH4 The combustible gas sensor is a general intelligent infrared gas sensor (hereinafter referred to as the sensor). It uses the principle of non-dispersive infrared (NDIR) to detect the hydrocarbon combustible gas in the air. It has good selectivity, no oxygen dependence, stable performance, long service life, and built-in temperature compensation. The sensor is a compact and high-performance sensor made by combining infrared absorption gas detection technology with micro-machining and sophisticated circuit design. It is easy to use and can be used as a substitute for catalytic sensors. It is widely used in various occasions where there are flammable and explosive gases.
