For measurements in aqueous solutions, provide approximately the same
stirring conditions for measuring as for calibrating.
NOTE
Prevent contact of the pH membrane to the beaker bottom to avoid
scratches on the pH membrane.
Subsequent
calibrations
The frequency of subsequent calibrations depends on the application. The
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
During short
measuring breaks
Immerse the electrode in reference electrolyte (KCl 3 mol/L, Ag
+
free). Prior
to the next measurement, shortly rinse the electrode with the test sample or
deionized water.
Overnight or
longer
Put the clean electrode in the watering cap that is filled with reference elec-
trolyte (KCl 3 mol/L, Ag
+
free).
NOTE
Do not store the electrode dry or in deionized water.
The electrode could be permanently damaged by this.
If the liquid in the watering cap has dried up, condition the electrode in
reference electrolyte (KCl 3 mol/L, Ag+ free) for at least 24 hours.
Junction
During longer storing periods, salt sediments may develop on the
watering cap. They do not affect the measuring characteristics
and can easily be removed with deionized water when the elec-
trode is put into operation again.
