Webb1 sep. 2024 · pH probe contains two electrodes (a sensor electrode and a reference electrode) to measure the hydrogen ion activity in the solution. The ion exchange generates a voltage, which is measured by a pH meter that converts the voltage to a readable pH value. It is a water quality sensor that measures the pH level of a liquid. WebbWhat is pH Measurement . pH Measurement specifies the degree of relative acidity or alkalinity of an aqueous solution at a given temperature. Theoretically, pH is derived from the word “Pondus Hydrogenii” which means “Potential Hydrogen” or Power of Hydrogen. Fig. 1 – Different Types of pH Meters
