The IOT-485-NH3N is a digital online ammonia nitrogen sensor with RS485 Modbus. It measures ammonia nitrogen concentration using an ion-selective electrode method. The ammonium ion-selective electrode directly detects ammonium ions in the water environment to determine ammonia nitrogen concentration. A pH electrode is used as a reference electrode for improved stability. The concentration of ammonia nitrogen during the measurement process is easily interfered by potassium ions, thus requiring potassium ion compensation.

The digital ammonia nitrogen sensor is an integrated sensor that is composed of ammonium ion selective electrode, potassium ion (optional), pH electrode and temperature electrode. These parameters can mutually correct and compensate the measured value of ammonia nitrogen, and meanwhile achieve the measurement for multiple parameters.

Application

It is widely used to measure the value of ammonia nitrogen in the nitrification treatment and aeration tanks of the sewage treatment plants, industrial engineering as well as river water.
