• Immerse the combination electrode in the solution in a vertical or slightly tilted
• Make sure the immersion depth is correct. The junction must be completely
• Provide approximately the same stirring conditions for measuring as for
The frequency of subsequent calibrations depends on the application. Many
meters provide an option where you can enter a calibration interval. After the
calibration interval has expired, the meter will automatically remind you of the due
calibration.

Storage

With the refilling opening open, immerse the combination electrode in
in reference electrolyte (KCl 3 mol/L, Ag+ free). Observe the minimum depth
of immersion. Prior to the next measurement, shortly rinse the combination
electrode with the test sample or deionized water.
Note
Prevent contact of the pH membrane to the beaker bottom to avoid scratches
on the pH membrane.
Put the clean combination electrode in the watering cap that is filled with
reference electrolyte (KCl 3 mol/L, Ag
Note
pH combination electrodes must not be stored dry or in deionized water. The
combination electrode could be permanently damaged by this. If the liquid in
the irrigation cap has dried up, condition the combination electrode in
reference electrolyte (KCl 3 mol/L, Ag+
Note
During longer storing periods, salt sediments may develop on the watering
cap. They do not affect the measuring characteristics and can easily be re-
moved with deionized water when the combination electrode is put into oper-
ation again.
