The Ammonia Nitrogen Sensor utilizes advanced ion-selective electrode technology to deliver highly accurate measurements of ammonium ions (NH₄⁺) in water. The sensor features a working electrode, reference electrode, ion-selective membrane, and electrolyte, allowing only ammonium ions to pass through the membrane and trigger a charge change. This generates a potential at the working electrode proportional to the ion concentration, while the transmitter applies the Nernst equation to convert this potential difference into precise ammonia nitrogen concentration readings. Independent of water color or turbidity, this sensor is ideal for continuous monitoring in industrial, agricultural, and domestic wastewater, offering rapid, reagent-free detection to support effective water quality management and eutrophication control.
