Use and care
Potassium electrodes are manufactured for use in 9180 Electrolyte Analyzers.
Proper care should be used in handling and storage of the electrode. Never use strong
or abrasive cleaners such as alcohol or amphyl on the electrode since these will
damage the plastic housing.
Store the electrode in a clean, dry place only after the electrode has been cleaned and
rinsed with distilled water and dried with a lint-free cloth.
The o-ring seal should be installed in the electrode during storage.
