Ammonium Nitrogen Sensor

[Product Description]
◼ IoT NH4 sensor equipped with both RS-485 and Wi-Fi web interface, allowing for remote or on-site monitoring directly via smartphone-no display unit or app required. It provides accurate and durable NH4 readings and can integrate with any global display system or software.
◼ Automatic Cleaning Function (Optional) : Includes a built-in micro air pump. The cleaning schedule is adjustable, featuring automatic cleaning mode that holds the last measured value and adjustable stabilization time—significantly extending maintenance intervals.
◼ Smartphone Web-Based Smart Calibration : Simply replace the standard solution bottle under the protective cap, then follow the guided calibration process via the smartphone web interface. Remote calibration is also supported, making the process extremely user-friendly.
◼ Smart AI Features : Includes notifications for calibration and automatic cleaning status, as well as self-diagnosis of electrode contamination or aging.

[Features]
◼ All-in-One Design : Built-in IoT transmission module and sensor; ready to operate upon power-up with all functions fully integrated.
◼ IP68 Submersible, Corrosion-Resistant Construction : Designed for direct immersion in water without the need for protective tubing.
◼ High-Durability, Isolated Signal Cable : Ready for direct use in the field with stable signal transmission and surge-isolated power and IoT communication lines.
◼ Temperature Compensation & Compliance : Includes temperature compensation and measurement method compliant with Taiwan EPA regulation NIEA W218.51C for automatic monitoring facilities.
◼ Smart Design with Calibration Memory : Calibration parameters are stored internally, allowing the sensor to be installed on-site immediately after calibration.
◼ Three-Point Calibration : Supports calibration using standard solutions or known-concentration samples.
◼ Maintains Last Reading During Calibration & Cleaning : Prevents false readings during calibration and automatic cleaning; displays live status such as "Calibrating," "Auto-Cleaning," "Stabilizing," or "Under Maintenance."
◼ Web & RS-485 Calibration Record Access : Allows querying of the latest three calibration records (date, slope, calibration points) via web interface or RS-485.

[Applications]
Sewage, groundwater, freshwater aquaculture, river and lake detection systems.
