BGT RS485 4-20mA Online Digital NH4-N/NH3-N Ion Ammonia Nitrogen Sensor with pH Compensation
Precision-engineered with industrial-grade materials for long-term stability in harsh environments. Features RS485/4-20mA dual output for seamless PLC/SCADA integration. Advanced ion-selective electrode technology ensures ±2% accuracy in NH4-N/NH3-N detection (0-1000ppm range). Built-in pH compensation eliminates false readings caused by water acidity fluctuations. IP68 waterproof housing (316L stainless steel + ABS) resists corrosion in wastewater, aquaculture, or industrial discharge monitoring. Calibration-free design reduces maintenance costs. Wide voltage support (12-24V DC) suits solar-powered setups. Applications: Real-time pollution control in rivers/lakes, aquaculture nutrient management, smart agriculture runoff monitoring, and industrial wastewater treatment compliance. Plug-and-play installation with optional mounting brackets for tanks/pipes. Global wholesale pricing available—bulk orders ship with ISO-certified calibration reports. Compatible with major water quality platforms (Modbus RTU).
