31.8 Stored buffer series for pH calibration
The temperature-dependent pH values of several common pH buffers are
stored in the system for automatic buffer recognition during pH calibra-
tion. Apart from the Metrohm buffer solutions other reference and techni-
cal buffers are also included in the tables.
The following tables provide an overview of the stored pH(T) series.
pH values printed in bold are the values for the reference temperature of
the respective buffer set.
pH values printed in italics are interpolated or extrapolated values, all the
others correspond to the manufacturer's specifications.
