pH Testing Instrument

A pH meter uses a glass electrode and a reference electrode to form a galvanic cell, measuring the potential difference corresponding to 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 water quality in fields such as chemical engineering, environmental protection, and food production.
Selection
When selecting, consider measurement accuracy and range, check the compatibility of the electrode material with the liquid to be measured, and confirm the temperature compensation function. Portable types are suitable for field use, while benchtop types are ideal for continuous measurement in the laboratory. Pay attention to the availability of calibration solutions and the maintenance cost of electrodes.
