IP66 OTA RS485 NH4-N Sensor For Sewage And Industrial Wastewater
The dissolution of the measurement result of the ammonia nitrogen sensor is interfered by potassium ions, so 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.
