The detection principle of Handheld Ammonia Gas NH3 Detector Meter Tester Monitor Range 0-100PPM Sound Light Alarm Gas Analyzers AR8500
The detection principle of the ammonia gas detector generally includes electrochemical or semiconductor principle sensors. The sampling methods are divided into pump suction type and diffusion type. The ammonia gas detector is mainly composed of sampling, detection, indication and alarm. When the ammonia gas in the environment diffuses or sucks to the sensor, the sensor converts the ammonia gas concentration into A certain size of the electrical signal, and then the concentration value will be displayed by the display
