Temperature influence in pH measurement.

The pH value depends on the temperature of the material to be measured, and the slope (mV/pH) of the measuring electrode increases as the temperature rises. Therefore, every pH measurement also includes a temperature measurement. If calibration and subsequent measurement are carried out at approximately the same temperature (20...25°C), temperature compensation is not necessary. If, on the other hand, the temperature of the test sample deviates from the calibration temperature, the temperature must be measured. It can be assumed that a sample temperature deviation of about 10°C compared to the calibration temperature already results in a measurement error of about 0.15 pH.

For pH measurements in water with a low conductivity < 50µS, the sample should be inoculated with KCl to make it more conductive. Inoculation increases the conductivity of the water without changing the pH. In general, however, it must be assumed that pH measurements in very soft water are more difficult and a higher error (order of magnitude 0.1 - 0.3 pH) must also be expected. Gel electrodes are not suitable for such measurements.
