- 【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 Yewhick 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
- 【Safety of Use】The pH/EC controller has a fuse protection function. When the abnormal current reaches a certain height, the fuse will be blown to cut off the circuit to protect the entire circuit and avoid accidents. It is also possible to turn off the controller via the knob when the set value is not reached but needs to be turned off.
- 【Wide application】This nutrient meter with the controller can monitor pH/EC/temperature, mainly used for nutrient monitoring and automatic adjustment of hydroponic growing systems, water quality monitoring for greenhouse planting, and agricultural irrigation. It can also be used for water quality safety monitoring of water sources and drinking water.
