ME4-NH3 Ammonia Sensor
The ME4-NH3 sensor is a constant-potential electrolytic-type ammonia (NH3) sensor. Inside the sensor, NH3 undergoes a series of redox reactions that release electrical charge, generating an electric current. The magnitude of this current is directly proportional to the concentration of NH3; therefore, the NH3 concentration can be determined by measuring the current.
