Industrial RS485 Water Quality Ammonia Nitrogen & pH Sensor

This industrial-grade ammonia nitrogen sensor probe and housing feature an integrated design, resulting in a simple and convenient structure. It is used for accurately measuring ammonia nitrogen concentration in water (including free ammonia (NH3) and ammonium ions (NH4+)), with a measurement range of 0~100 mg/L, a resolution of 0.01 mg/L, and an accuracy of ±3% FS.

The ammonia nitrogen sensor is equipped with an RS485 communication interface and supports the standard ModBus-RTU protocol. Tutorials are provided for connecting the sensor to an Arduino development board and DFRobot LoRaWAN, allowing for quick setup of a test environment and real-time data monitoring. The sensor features automatic pH and temperature compensation, ensuring accurate and reliable data output even under varying environmental conditions.

The ammonia nitrogen sensor is rigorously calibrated before leaving the factory and is ready for use upon arrival, requiring no further calibration. It supports two-point electrode calibration via register settings, allowing users to quickly optimize measurement accuracy after prolonged use. With an overall waterproof rating of IP68, it can be submerged in water for extended periods, making it suitable for applications such as aquaculture, wastewater treatment, and environmental monitoring.
