[Product Description]
◆ IoT NO3 analyzer with RS-485 and Wi-Fi web interface, and it can monitor by remote and in-situ with mobile phone which is without meter and app.
◆ Automatic cleaning function (optional):Including Micro air pump, cleaning scheduling(adjustable), keeping the last reading(during auto cleaning), and stabilization time(adjustable), that is able to extend maintenance period easily.
◆ Smart calibration function: Switching protective cover to standard solution cover, and it calibrates with phone webpages.
◆ Smart AI function: calibration/auto-cleaning notification, self-judgment of stain and electrode degree of aging..etc.
◆ IP68 integrated design: The NO3 sensor can put into the application environment such as river/reservoir/tap water/ sewage..etc. Accurate and durable NO3 value can be provided to any meter or software in the world. -----

[Features]
◆ Integrated design, and built-in IoT transmission and sensor.
◆ IP68 submerged type and corrosion resistant material which can put into water without protective sleeve.
◆ It can be operated by delivery of current, and all functions are built-in.
◆ Ultra-low power consumption, it is suitable for large-scale deployment of green energy IoTs.
