If the pH meter is used frequently, the pH meter accuracy should be checked before measuring an unknown pH. For this purpose, before measuring an unknown pH of a solution, a check must be carried out against a standard buffer solution with pH that is the nearest to the target solution. However, if the pH meter is used occasionally, before measuring an unknown pH of a solution, a two- or three-buffered calibration must be done to standardize the measuring.
