Digital PH/ORP Dual Sensor For Drinking Water Pipes – MODBUS RTU, Support For The Installation Of The Flow Cell
1.Product Overview
The KNF-101-2 pH/ORP sensor is a digital sensor product specially developed by our company for online monitoring of drinking water quality. It integrates digital circuits within the sensor and can simultaneously monitor three parameters: pH, ORP concentration, and temperature in water. It adopts an RS-485 transmission interface and Modbus-RTU communication protocol. It can be widely applied in online monitoring of drinking water, surface water, groundwater, sewage, etc.
2.Sensor features
1. Power isolation design ensures stable signal without interference;
2. Standard Modbus-RTU protocol, easy to connect and use;
3. One sensor can measure pH and ORP simultaneously;
4. Protection grade IP68, capable of long-term underwater operation.
