B.2.9 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 measurement 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 temperature is
measured.
