pH Measurement Instrument

A pH meter forms a galvanic cell using a glass electrode and a reference electrode to measure the potential difference generated by the concentration of hydrogen ions in a solution. It is used to detect the acidity or alkalinity of liquids and to monitor reaction conditions and product quality in fields such as chemical engineering, environmental protection, and food production.
Selection
Select the electrode material based on the measured medium; use special glass membranes for strong acids and bases. Consider temperature compensation and calibration stability, and regularly calibrate electrodes with standard buffer solutions. Portable models are suitable for fieldwork, while benchtop versions offer higher precision for laboratory use.
