DO Sensor

■IoT DO 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 bottle, 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 DO sensor can put into the application environment such as river/reservoir/tap water/ sewage/ seawater.. etc. Accurate and durable DO value can be provided to any meter or software in the world. ----- [Features] ■Caps can be quickly replaced. ■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 DO sensor is equipped with temperature compensation, atmospheric pressure , and salinity compensation. ■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. ■Sensing film life can be used up to 1～2 year. ■Optional auto-cleaning function, extending the maintenance cycle about 2~3 times. ■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 bottle on site, it is convenient for calibration. ■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/ under maintenance ). ■The latest thrice calibration records (date/slope/calibration point) can be inquired. ----- [Applications] : Aquaculture、Seawater、Sewage、Subterranean water River、plant nutrient solution.
