CH4 Sensor

CH4 gas sensor is a dedicated intelligent infrared gas sensor (hereinafter referred to as the sensor), using the non-dispersion-infrared (NDIR) principle to detect the presence of hydrocarbon combustible gas in the air, with good selectivity, no oxygen dependence, stable performance, long life: built-in temperature compensation.The sensor is a compact high performance sensor which combines mature infrared absorption gas detection technology with micro-machining and sophisticated circuit design.Easy to use, can be used directly to replace the catalytic combustion components, widely used in the presence of flammable, explosive gas in a variety of occasions.
