Aging
Please note that every (combination) electrode undergoes a natural aging
process. The response time increases and the slope decreases with the age
of the (combination) electrode. The following factors shorten the lifetime con-
siderably:
Incorrect storage
Special measuring conditions (e.g. organic solutions, frequent measure-
ment with high concentrations of interfering ions)
High temperatures
High changes in temperature
The warranty does not cover damage caused by measuring conditions and
mechanical damage.
Maintenance
Combination electrodes:
Refill any used up bridge electrolyte.
Install an exchange membrane cap.
NOTE
Never pull the connection cable of the electrode.
The cable might be damaged.
Storage
Condition the electrode in standard solution.
Rinse the combination electrode with deionized water and dry it. Then put on
the storage vessel and store the electrode upright.
Remove the bridge electrolyte, then rinse the combination electrode with
deionized water and dab it dry with a clean paper towel. Store the combi-
nation electrode in the storage vessel in a dry place. For the following
measurement, prepare the combination electrode as described in section
C
