The subject of this booklet is the potentiometric measurement of pH. This is the way in which pH is defined and is the optimal method for obtaining precise results. Reliable and accurate measurements depend on a number of factors: the quality of the equipment used, the electrode type, the accuracy of the calibration, the maintenance level, good laboratory practice and so forth. The scope of this booklet is to discuss these various factors and their importance. Hints and recommendations are given and short theoretical sections are included. All the necessary information is therefore at hand to help you to obtain precision results in practice.
