SMATRUL Smart WiFi pH EC Monitor with Controller, Hydroponics System Nutrients Tester

【WIFI Online pH/EC Monitor and Data Logger】This 24/7 water quality monitor for hydroponic growing systems can monitor pH, EC and temperature online, and supports exporting daily measurement data in APP. After setting the high and low values according to your needs, the controller will automatically turn on and alarm if the set value is exceeded. 【Automatic Control】The WiFi pH EC monitor can be connected to a CO2 pump that adjusts pH and a hydroponic nutrient solution that adjusts EC. When the measured value exceeds the set value, the controller will send a signal to the solenoid valve to automatically turn on the CO2 pump/nutrient solution switch until the set value is reached. 【Remote Monitoring】This hydroponic nutrients tester can remotely monitor the hydroponic growing system online through APP, run automatically throughout the day and automatically adjust beyond the limit, with real-time data transmission, which is convenient to control and predict water quality changes at any time
