CALIBRATING THE SYSTEM
When the electrode system has been correctly installed and all
electrical connections made to the associated pH meter, the
system is ready for calibration by immersing the electrodes in
buffer solutions of a known pH value.
Full details of the procedure are given in the instruction manual for
the pH meter, to which reference should now be made.
The method for immersing the electrodes in the buffer solutions is
simply by removing the electrode holder unit from its process
fitting and dipping the electrodes in a small beaker of the
appropriate buffer solution. For dip systems wash the electrodes
with demineralised water and immerse in suitably sized beakers
using two buffer solutions.
