Aging
ORP electrodes are consumables. Every ORP electrode undergoes a natural
aging process. Extreme operating conditions can considerably shorten the
lifetime of the electrode. These are:
Strong acids or lyes, hydrofluoric acid, organic solvents, oils, fats, bro-
mides, sulfides, iodides, proteins
High temperatures
High changes in pH and temperature.
The warranty does not cover failure caused by measuring conditions and
mechanical damage.

Storage
Immerse the electrode in reference electrolyte (KCl 3 mol/L, Ag
to the next measurement, shortly rinse the electrode with the test sample or
deionized water.
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.
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.
