Measurement Principle
Ammonia nitrogen concentration is measured using the ion-selective electrode method. The ammonia nitrogen ion-selective electrode directly detects ammonium ions in the water environment to determine the ammonia nitrogen concentration. A pH electrode is used as a reference electrode for better stability. The ammonia nitrogen sensor consists of an ammonium ion-selective electrode, a pH electrode, and a temperature electrode integrated into a single sensor. These parameters can mutually correct and compensate for the ammonia nitrogen measurement value while enabling multi-parameter measurement.
Main Features
l Integrated ammonia nitrogen electrode, pH electrode, and temperature electrode into one unit
l The ammonia nitrogen electrode allows separate replacement of the membrane head and electrolyte, with low consumable costs and simple maintenance
l Digital sensor with strong anti-interference capability and long transmission distance
l Standard digital signal output enables integration and networking with other devices without a transmitter
l Convenient and quick on-site installation of the sensor, supporting plug-and-play
l Sensor features reverse polarity protection for power supply and protection against incorrect power connection to RS485 A/B terminals
l Equipped with time display, data storage, and historical data review functions
l Optional wireless data transmission module
Typical Applications
l Monitoring ammonia nitrogen levels in nitrification treatment and aeration tanks of wastewater treatment plants, industrial processes, and river water
