The detection principle of Ningbo Gaopin ammonia detector generally includes electrochemical or semiconductor principle sensor. The sampling method is divided into pump suction type and diffusion type, mainly consisting of sampling, detection, indication and alarm. When the ammonia gas in the environment diffuses or suction reaches the sensor, the sensor converts the ammonia concentration into an electrical signal of a certain size, and then the concentration value is displayed by the monitor.
