How to use

Remove the pH meter from its storage container and switch it on. Rinse the electrode with distilled or tap water and immerse it in the sample solution so that the electrode is covered. Wait until the reading stabilises, then press HOLD to freeze the displayed values if needed. After measurement, rinse the electrode and return the device to its storage container filled with the supplied special solution to prevent the electrode from drying out. Calibrate the meter regularly following the manufacturer’s instructions to ensure continued accuracy.

Usage recommendations

The pH results depend on temperature; use the automatic temperature compensation and calibrate the device before critical measurements. Clean the electrode after each use and store it in the supplied solution to extend electrode life. Avoid prolonged exposure to strong acids, bases or solvents that may damage the electrode.
