A pH meter is a statistical tool that monitors the hydrogen-ion activity in water-based solutions, determining its acidity or alkalinity represented as pH. pH Meter It measures pH on a scale of 0 to 14. The proportion of hydrogen ions (H+) to hydroxyl ions (OH-) determines a substance's pH value.
10 Best Digital pH Meters
A pH meter is a piece of laboratory equipment used to measure hydrogen ion concentrations (i.e., acidity and alkalinity) in a water-based solution expressed as pH. It measures the difference in electrical potential between the pH electrode and the reference electrode.

A basic block diagram of a digital pH meter is shown in Fig. 6.20. The dual slope circuit produces a pulse which has a duration proportional to the input signal voltage, that is, a T pulse width signal. The pulse width is converted to a digital signal using the pulse to turn an oscillator On or Off, generating a count digital signal.
