Digital RS485 Optical Nitrate Nitrogen Sensor NO3-N–CS6802CD
Digital Nitrite Nitrogen Sensor is an online analytical device for continuous measurement of nitrite‑nitrogen (NO₂⁻‑N) concentration in water and wastewater. It operates on the ion‑selective electrode (ISE) principle or an electrochemical method with a polymeric membrane, providing high selectivity and rapid response without the need for reagents or sample preparation. The sensor integrates a built‑in reference electrode and automatic temperature compensation (ATC) for accurate, drift‑free readings over a typical range of 0–10 mg/L. It directly outputs digital data via RS‑485 (Modbus RTU), enabling plug‑and‑play integration into SCADA or IoT platforms. Its durable, waterproof (IP68) housing and low‑maintenance design are suitable for continuous monitoring in aeration tanks, effluent channels, drinking water sources, and aquaculture systems. Nitrite is an intermediate product of nitrification and denitrification; excess levels are toxic to fish and indicate incomplete biological treatment. By delivering real‑time nitrite data, the sensor helps optimize aeration and carbon dosing, improve nitrogen removal efficiency, reduce energy and chemical costs, and ensure compliance with discharge limits (e.g., <1 mg/L for drinking water). Compared to colorimetric analyzers, this ISE‑based sensor requires no chemical reagents, no sample filtration, and has faster response, lower operational cost, and simpler maintenance. Its digital output supports remote calibration, self‑diagnostics, and unattended continuous water quality monitoring, making it an essential tool for wastewater treatment plants, environmental agencies, and aquaculture farms. The sensor can be directly submersed into tanks or channels, providing real‑time data without pumping or sample conditioning, thus ensuring rapid detection of process upsets and timely corrective actions. -
