What Is a pH Meter?
A pH meter is an electronic analytical instrument used to measure the acidity or alkalinity (pH value) of liquid solutions. It determines hydrogen ion activity using a sensitive glass electrode and reference electrode, providing significantly higher accuracy than pH test strips or indicator papers. Modern digital pH meters often include automatic temperature compensation (ATC), multi-point calibration, and digital data storage to ensure reliable results across laboratory and industrial applications.
How Does a pH Meter Work?
A pH meter measures the electrical potential difference between a glass electrode and a reference electrode. This electrical signal is converted into a precise pH value displayed on the instrument.
The measurement process typically includes:
• Immerse the electrode into the sample.
• The glass electrode detects hydrogen ion activity.
• The meter calculates the pH value.
• Automatic temperature compensation adjusts the reading when temperature variations may affect accuracy.
• Results are displayed instantly on the digital screen.
