Storage
During short
measuring breaks
Immerse the electrode in the reference electrolyte with the refilling opening
open.
Prior to the next measurement, shortly rinse the electrode with the test
sample or deionized water.
Overnight or
longer
Insert the clean electrode into the watering cap filled with reference electro-
lyte and shut the refilling opening.

Aging
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.

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.
