Ammonium (NH₄⁺ / NH₃) Sensor – RS485 Modbus, 4–20mA Output, Submersible
Online ammonium ion sensor for real-time monitoring of NH₄⁺ / NH₃ in water. Designed for wastewater, environmental, and aquaculture applications with RS485 and 4–20mA outputs.
This ammonium ion sensor is designed for continuous, real-time monitoring of NH₄⁺ (ammonium) and NH₃ (ammonia) concentrations in water. It is a critical parameter for assessing nutrient levels, biological activity, and water quality in wastewater treatment, aquaculture, and environmental monitoring applications.
The sensor utilises an ion-selective electrode (ISE) measurement principle to deliver reliable ammonium readings across a wide concentration range. With high sensitivity and stable performance, it enables early detection of nutrient changes and supports process optimisation and compliance monitoring.
Designed for submerged operation, the probe features an IP68-rated housing and durable ABS construction for long-term use in harsh environments. It comes with a standard cable length and can be customised for specific installations.
With both RS485 (Modbus-RTU) communication and 4–20mA output, the sensor integrates seamlessly into PLCs, RTUs, SCADA systems, and cloud platforms for remote monitoring, alarms, and analytics.
