Setup pH temperature
compensation
The relationship between pH and the output signal from the pH electrode is temperature
dependent. For accurate measurements during temperature changes, the pH measure-
ment can be temperature compensated. In normal applications, when the temperatures
of the buffers and calibration buffers are identical, temperature compensation is not
necessary.
When using temperature compensation, it is important that the temperature of the pH
electrode is the same as that of the conductivity flow cell since that is where the temper-
ature is measured.
