Portable pH Tester

The portable pH tester utilizes a glass electrode and a reference electrode to form a galvanic cell, measuring the potential difference generated by the hydrogen ion concentration in the solution, which is then converted by the circuit into a pH value for display. It is used for on-site rapid detection of liquid acidity or alkalinity and is suitable for applications such as water quality monitoring, chemical production, and food processing.
Selection
When selecting, consider that the measurement range covers usage requirements, accuracy meets testing standards, and it includes temperature compensation functionality. Check whether the electrode material is corrosion-resistant and whether the device's protection rating is suitable for the operating environment. Ensure that the calibration method is straightforward, data storage features are practical, and battery life matches the workload intensity.
