Up to nine different buffer solutions of various types or manufacturers can
be entered here.

Type

Buffer solution type or manufacturer

Metrohm | NIST | DIN | Fisher | Novartis | Ingold |

Merck | Beckman | Radiom. | none | custom

As the buffer solutions can have very different composi-
tions, it is necessary to enter the correct buffer type so
that the temperature correction function can be correctly
applied during the calibration.
If your type of buffer is not given in the list you should
select 'none'.
During the calibration the determined values are com-
pared with the buffer solution information (theoretical
value, temperature for automatic temperature meas-
urements) and subjected to a plausibility test, see page
118. If this leads to interfering error messages with '

ex-

otic' buffers or 'extraordinary' sensors, then select the
buffer type 'custom' for user-defined buffer types. No
plausibility test is carried out in this setting.

Nominal pH of the buffer

pH -20…20

The buffer solutions offered by the above-mentioned
manufacturers are stored in the Titroprocessor with their
nominal values. The entry field has a selection list in
which various buffer values depending on the given
buffer type or manufacturer can be selected. It is also
