IDP Integrated Digital pH Sensor

Operating Principle

The IDP Integrated Digital pH Sensor uses a composite electrode composed of a glass electrode and a reference electrode to measure the pH value of water. The potential of the reference electrode inside the glass electrode remains constant and is independent of the pH of the solution being measured. When the glass bulb is immersed in the solution with varying H⁺ concentrations, the analyzer reads the potential difference between the stable potential of the reference electrode and the potential generated by the glass bulb. This difference is used to determine the pH value.
