Measured temperature is the temperature in the conductivity flow cell, which
can differ from the ambient temperature.
When running chromatography using organic solvents, it is recommended
that the pH electrode is removed and the dummy electrode inserted in its place,
as organic solvents will cause pH electrode degeneration.
