Online Digital NH3-N Potassium Ion Compensation Ammonia Nitrogen Sensor RS485 CS6015DK

Short Description:

Digital NH₃-N Ammonia Nitrogen Sensor is an online analytical device for continuous measurement of ammonia nitrogen concentration in water and wastewater. It typically operates on the ion-selective electrode (ISE) principle combined with a gas-permeable membrane. Ammonia gas diffuses through the membrane into an internal electrolyte, causing a pH change that is directly proportional to the NH₃-N concentration. The sensor features automatic temperature compensation (ATC), a built-in reference electrode, and direct digital output (RS-485, Modbus RTU) for seamless integration into SCADA or IoT platforms. Its robust, waterproof (IP68) housing ensures reliable performance in harsh environments. Common applications include municipal wastewater treatment (aeration tank and effluent monitoring), aquaculture (toxicity control), drinking water source protection, and industrial process control. Typical range is 0–1000 mg/L with fast response and low maintenance. Compared to colorimetric analyzers, this sensor requires no reagents, no sample preparation, and provides real-time data. It helps optimize aeration, reduce energy and chemical costs, ensure regulatory compliance, and protect aquatic life. Its digital design eliminates signal interference and enables plug‑and‑play connectivity, remote calibration, and long-term stability, making it essential for unattended, continuous water quality monitoring.
