Ammonia Nitrogen Water Quality Sensor

Overview Ammonia nitrogen is a common pollutant found in industrial, agricultural, and domestic sewage. Ammonium nitrogen depletes dissolved oxygen in water bodies and leads to eutrophication. Ammonium ions are measured using the ion-selective method, which consists of a working electrode, a reference electrode, an ion-selective membrane, and an electrolyte. Only the ammonium ions to be measured can pass through the ion-selective membrane and undergo a charge change, generating a potential at the working electrode that is proportional to the ion concentration and a constant potential at the reference electrode. The controller is based on the Nernst equation, which measures the potential difference between the working and reference electrodes and converts it to the ammonia nitrogen concentration based on the principle of potentiometric measurement, independent of coloration and turbidity. It is suitable for online and portable monitoring of municipal sewage, domestic sewage, agricultural sewage, industrial sewage, process control, nitrification treatment and aeration tanks, etc. It is suitable for integrated applications such as buoy monitoring, floating discharge monitoring and vessel monitoring Features Quick measurement, the shortest measurement cycle is 1 second RS485 communication mode, can quickly connect the meter controller, control the sensor IP68 protection grade, can be used in harsh environments Low power consumption, can be powered by battery, convenient for equipment deployment Application Domestic sewage Surface water, ground water Industrial sewage Sewage treatment process
