Automatic Temperature Compensation in pH Measurement

WebTemperature also affects the pH electrode slope. 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 ...
