The 4N-CH4L combustible gas sensor is a general-purpose intelligent infrared gas sensor (hereinafter referred to as the sensor). It uses the non-dispersive infrared (NDIR) principle to detect hydrocarbon combustible gases in the air, exhibiting excellent selectivity, no oxygen dependence, stable performance, long lifespan, and built-in temperature compensation. This sensor is a compact, high-performance device manufactured by tightly integrating infrared absorption gas detection technology with micromachining and sophisticated circuit design. It is easy to use and can be used as a replacement for catalytic sensors, widely applicable in various situations where combustible and explosive gases are present.
