High-Accuracy Industrial Digital RS485 Ammonia Nitrogen (NH4+) Sensor for Water Quality Monitoring

Short Description:

The Ammonia Nitrogen (NH4+) Sensor delivers precise and reliable measurements for water quality analysis across diverse environments. Designed with eco-friendly polymer plastic, this sensor ensures chemical resistance and durability in harsh industrial or outdoor settings. It features an isolated power supply (9-24VDC) for stable performance (±5% accuracy) and anti-interference capabilities, even in electromagnetically noisy conditions. Custom calibration via forward/reverse curves allows flexibility for specific measurement scenarios, while its compact design (31mm*200mm) and RS-485 MODBUS output enable seamless integration into existing water quality systems. Ideal for surface water, sewage, potable water, and industrial effluent testing, this sensor minimizes maintenance with an easy-to-clean, pollution-resistant structure.
