YJJ Used for gas detection ammonia gas sensor (NH3 sensor)TGS826 in refrigerators

Product introduction

I. product description of ammonia gas sensor (NH3 sensor)TGS826

The sensor sensor of figaro is composed of SnO2 semiconductor, whose conductivity in clean air is very low. When the detected gas exists in the air, the higher the concentration of the gas, the higher the conductivity of the sensor will be. 

Using a simple circuit, the change in conductivity can be converted into a signal output corresponding to the concentration of the gas. 

Ammonia gas sensor (NH3 sensor)TGS826 has a very high sensitivity to ammonia gas, which can detect ammonia gas in the air as low as 30ppm. It is an ideal critical safety detection sensor for refrigerant, and can also be used for ammonia gas leakage detection in the agricultural field. 

Ii. Application of ammonia gas sensor (NH3 sensor)TGS826

Ammonia gas sensor TGS826 (NH3 sensor TGS826) is mainly used in refrigerator gas detection, ammonia gas leakage detection in cold storage, and risk control of agriculture and breeding industry. 

Characteristics of ammonia gas sensor (NH3 sensor)TGS826:
