Infrared Methane Sensor (CH4 Sensor)
The MH-440D infrared methane sensor is a universal, intelligent, and miniature sensor. It utilizes the non-dispersive infrared (NDIR) principle to detect CH4 present in the air, offering excellent selectivity, no oxygen dependence, stable performance, and a long lifespan. It has a built-in temperature sensor for temperature compensation. This sensor is easy to use and features complete gas detection, analog voltage signal output, and serial communication functions.
