online ammonia nitrogen detector

measuring principle

The ammonia nitrogen concentration was measured by the ion-selective electrode method. The ammonia ion selection electrode directly detects the ammonium ion in the water environment to determine the concentration of ammonia nitrogen. The pH electrode was used as the reference electrode to obtain better stability.

Because the dissolution of the measurement result of the sensor is disturbed by the potassium ion, so when the concentration of the potassium ion in the water is high, the potassium ion compensation is needed.

Ammonia nitrogen sensor consists of ammonium ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. These parameters can correct the measurement value of ammonia nitrogen to each other and realize multi-parameter measurement.
