The pH online sensor adopts the glass electrode method and features a corrosion-resistant housing. It is equipped with a built-in NTC temperature sensor for automatic temperature compensation, minimizing the impact of temperature on measurement accuracy. The sensor supports RS485 communication and the standard Modbus protocol.
The sensor collects the potential difference between the reference electrode and the glass hydrogen ion indicator electrode, as well as the resistance value from the thermistor to obtain the water temperature. Based on the Nernst equation, the potential is then converted into a pH value.
