WebNov 29, 2024 · 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. If the concentration of [H+] exceeds that of ... WebThe term pH is derived from “p,” the mathematical symbol for negative logarithm, and “H,” the chemical symbol for Hydrogen. More accurate pH measurements are obtained with a pH meter. A pH measurement system consists of three parts: a pH measuring electrode, a reference electrode, and a high input impedance meter.
