Note
The platinum electrode (1) should be completely covered during the pretreat-
ment but the electrode must not be immersed in the solution up to the refer-
ence system with the hole junction (2) (see following figure).
Note
Detailed information on activating platinum electrodes, such as how to pro-
duce the clorina solution, is given in the WTW application report entitled R

Storage
During short
measuring breaks
Immerse the combination electrode in reference electrolyte (KCl 3 mol/L, Ag
+
free). Prior to the next measurement, shortly rinse the combination electrode
with the test sample or deionized water.
Overnight or
longer
Put the clean combination electrode in the watering cap that is filled with
reference electrolyte (KCl 3 mol/L, Ag
+
free).
Note
The combination electrode must not be stored dry or in deionized water. The
combination electrode could be permanently damaged by this.
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.
