Pen-Style Digital pH Meter

The pen-style digital pH meter detects the concentration of hydrogen ions in a solution through a glass electrode and converts the potential difference into a digital pH value for display. It is used for on-site rapid testing of liquid acidity and alkalinity, commonly found in water quality monitoring, food processing, and daily laboratory inspections.
Selection
When selecting, consider that the measurement range covers the common pH intervals, and the accuracy meets basic needs. Check whether the electrode material is resistant to chemical corrosion, and the body should be waterproof and drop-resistant. The calibration function should be simple, and the battery life should be suitable for field use.
