Webb28 apr. 2024 · The pH electrode behaviour follows the Nernst equation: E = E0 + 2.303 (RT/nF) log aH+ where slope, also called sensitivity, is denoted by -2.303 RT/nF and pH is equal to -log aH+. 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. Click image to enlarge. WebbTemperature Calibration and Correction. We use two temperature-measuring devices in the laboratory — thermometers and thermistors — and they both require calibration. For the thermometers, which are mostly mercury-filled, calibration is simple: Allow the thermometer to equilibrate in an ice/water bath and record the apparent T .
