The most common reasons for pH meter error is dry storage of the electrode and electrode contamination. These cause loss of accuracy, reduced performance, and slower response times. Avoid placing pH electrodes in harsh chemicals especially those of high concentration or extreme pH e.g. pH Up.

These can damage electrodes or increase the need for electrode maintenance. Thoroughly clean the electrode after use and always store your pH meter with the cap firmly in place. Frequency of meter calibration is crucial and will optimize your pH meter’s performance.
