NO3 Sensor

[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. ◆ The high-strength isolated cable can be put to use directly, and the signal is stable. ◆ The NO3 sensor is equipped with temperature compensation and measurement (in accordance with NIEA W218.51C). ◆ The power and IoT communication are equipped with surge protection. ◆ With dual digital communication of RS-485 and Wi-Fi. ◆ Standard Modbus RTU and can connect to the global IoT. ◆ Wisdom design, storing parameter calibration, it can be installed directly on site after calibration. ◆ Operating with mobile web pages, it is convenient to on-site operation. ◆ Switching protective cover to standard solution cover on site, it is convenient for calibration. ◆ With 3-point calibration, and the calibration point can be set. ◆ During calibration and auto-cleaning, keep the last reading value to avoid misoperation, and it read the state at the same time (calibrating/auto-cleaning/stabilizing). ◆ The latest thrice calibration records (date/slope/calibration point) can be inquired. ----- [Applications] : Sewage, drinking water, Subterranean water, Aquaculture, River and lake detecting system.
