Further minimization of this error in both temperature compensating and non-temperature compensating pH meters can be calibrating the instrument and electrode in pH buffers that are close to the expected measurement values for pH and at (or near) the same temperature as the solution to be measured. Temperature affects pH in a variety of ways for a detailed look at them see this article. Temperature compensation uses the measured conductivity and temperature readings of the sample and applies a coefficient or algorithm to calculate and report the conductivity value of the sample at the selected reference temperature. Figure 6: ATC and MTC settings in F-74 meter. Manual: where the user must dial or key in the solution temperature, and the meter then corrects the pH readings for changes in the electrode sensitivity. The After calibration, the pH meter generates slope at the measured temperature according to the Nernst equation. If the temperature is constant within several degrees C, then a manual compensator can be used. Since R, F, and n are constants, the slope changes with temperature and this effect can be compensated by a pH meter with ATC capability. Effects of Temperature on pH Just like pH buffers, the chemical compositions of samples may vary and therefore samples may react differently to temperature. Should I be looking for a meter that has this? In this case, the pH meter shows the default temperature 25C. During measurement, the pH meter applies the slope to calculate the pH values of samples.
