The MQ137 gas sensor has high sensitivity to ammonia and is also ideal for monitoring other organic amines (such as trimethylamine, ethanolamine, etc.). This sensor can detect various ammonia-containing gases and is a low-cost sensor suitable for multiple applications.
NH3-A1 is a 3-electrode electrochemical ammonia gas sensor with linear current output, easy signal processing, and high sensitivity. It is suitable for harsh environments such as poultry farms, pig farms, and other fields.
The ME3-NH3 electrochemical gas sensor is based on the electrochemical principle. The measured gas undergoes corresponding oxidation-reduction reactions on the working electrode and counter electrode, releasing charge and forming a current through an external circuit. The current magnitude is proportional to the gas concentration, enabling quantitative measurement of the target gas.
The ME4-NH3 sensor is a constant potential electrolytic NH3 sensor. NH3 undergoes a series of oxidation-reduction reactions inside the sensor, releasing charge to form a current. The current magnitude is proportional to the NH3 concentration, and the NH3 concentration can be determined by measuring the current.
The ammonia gas sensor (NH3 sensor) TGS826 has high sensitivity to ammonia and can detect ammonia concentrations as low as 30 ppm in the air. It is an ideal sensor for critical refrigerant leak detection and can also be used for ammonia leak detection in agricultural fields.
