Ingress Protection Rating
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.
