3.3.3 pH Adjustment
General information about pH adjustment
pH adjustment is always carried out after the main component has
been added (i.e. at the end of the mixing process).
For automatic pH adjustment 702 Titrinos from Metrohm are intended
for use. If the pH needs to be adjusted from both sides (without
changing the pH-Controller liquid), two 702 Titrinos are required as
pH-Controllers.
In the fields pH-Adjustment and pH-Controller define whether and how
the pH is to be adjusted.
If autonomous is selected for pH-Adjustment then none must not
be selected for pH-Controller. For autonomous a pH-Controller
must be used.
Window "pH-Adjustment Configuration"
The dialog window PH-ADJUSTMENT CONFIGURATION can be opened
by clicking on the button in the Main Window.
In the PH-ADJUSTMENT CONFIGURATION window the pH adjustment
procedure can be defined.
