Ammonia Nitrogen Sensors

The SensorsX SX-CNLCA Series is a self-cleaning ammonia nitrogen sensor designed for real-time water and wastewater monitoring. It uses an ion-selective electrode method with automatic pH and temperature compensation, requires no chemical reagents, and features an integrated cleaning brush for reduced maintenance. With RS-485 Modbus communication, IP68 protection, and an NH4-N measurement range of 0–100 mg/L, it is well suited for continuous industrial water-quality monitoring.
