Product Details

 

MH-440DInfrared sensorIs a universal, intelligent, micro-sensor, the sensor using non-dispersive infrared (NDIR) principle of the presence of CH4 in the air to detect, with good selectivity, oxygen-free dependence, stable performance, long life. Built-in temperature sensor, can be temperature compensation. TheInfrared sensorEasy to use, with a complete gas detection, analog voltage signal output and serial communication function; can be directly used to replace the catalytic combustion components, widely used in the presence of flammable, explosive gas of various occasions.

 

 

Sensor characteristics
