Nitrate Sensor

[Product Description]
◼ IoT NO3 sensor equipped with both RS-485 and Wi-Fi web interfaces, allowing for remote or on-site monitoring directly via smartphone-no display unit or app required. Provides accurate and stable NO3 readings, compatible with any global display unit or software.
◼ Automatic Cleaning Function (Optional) : Includes a built-in micro air pump. Adjustable cleaning schedule, automatic cleaning with last-value hold and stabilization time settings. Significantly extends maintenance intervals.
◼ Smartphone Web-Based Intelligent Calibration : Simply replace the standard solution bottle under the protective cap, and follow the guided calibration process via smartphone web browser. Supports remote calibration—extremely user-friendly.
◼ Smart AI Functions : Notifications for calibration and auto-cleaning status. Intelligent diagnostics for electrode contamination or aging levels.



[Features]
◼ Integrated Design : Built-in IoT transmission and sensor module. Fully functional upon power-up—no additional hardware required.
◼ IP68 Submersible and Corrosion-Resistant Housing : Designed for direct deployment in water without the need for a protective sleeve.
◼ High-Strength Isolated Cable : Ready for direct immersion. Ensures stable signal transmission with surge isolation protection for both power and IoT communication.
◼ Temperature Compensation & Regulatory Compliance : Measurement method complies with the Environmental Protection Administration’s standard NIEA W218.51C for automatic monitoring equipment.
◼ Smart Configuration : Calibration parameters are stored internally. After calibration, the device can be directly installed in the field without reconfiguration.
◼ Three-Point Calibration : Supports calibration using standard solutions or samples with known concentrations.
◼ Last Value Hold During Calibration and Auto-Cleaning : Prevents erroneous readings by retaining the last measured value. Status indicators show real-time state—Calibrating, Auto-Cleaning, Stabilizing, or Maintenance.
◼ Calibration Record Access : Last three calibration records (date, slope, and calibration points) can be retrieved via web interface or RS-485.

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