A pH Meter is a scientific instrument that measures the hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH[2]  The pH meter measures the difference in electrical potential between a pH electrode and a reference electrode, and so the pH meter is sometimes referred to as a ”potentiometric  pH meter”.

The difference in electrical potential relates to the acidity or pH of the solution.
