XDB1203-1A Series PH Sensor

Water quality analysis PH sensor is an important device used to measure the acidity and alkalinity of water. It usually uses an electrochemical system composed of a glass electrode and a reference electrode to measure the concentration of hydrogen ions in water and then determine the PH value. When the sensor is immersed in water, the special membrane on the surface of the glass electrode responds to the hydrogen ions in the water. By measuring the potential difference between the electrodes, and then through specific conversion and calculation, the accurate PH value is obtained.
