IP66 OTA RS485 NH4-N Transmitter For Sewage Controller For Industrial Wastewater

The ion-selective electrode method is used to measure the ammonia nitrogen concentration. The ammonia ion selective electrode directly detects the ammonium ion in the water environment to determine the concentration of ammonia nitrogen. Use a pH electrode as a reference electrode to obtain better stability.

Because the dissolution of the sensor's measurement results is interfered by potassium ions, when the potassium ion concentration in the water is high, potassium ion compensation is required.

The ammonia nitrogen sensor is composed of ammonium ion selective electrode, potassium ion (optional), pH electrode, and temperature electrode to form an integrated sensor. These parameters can mutually correct the measured value of ammonia nitrogen and realize multi-parameter measurement at the same time.
