Digital pH Sensor

The digital pH sensor adopts composite electrode technology. The sensor has a built-in temperature sensor, which automatically compensates the temperature. The composite electrode has a longer life and is suitable for online long-term monitoring environments. The sensor adopts RS485 output and Modbus protocol, which can realize networking and system integration without a controller.
