Storage
Between two
measurements
Store the electrode in air.
Overnight to one
week
Put the electrode into diluted aqueous standard solution with
the filling opening open. To avoid a contamination of the
bridge electrolyte with standard solution, the level of the
bridge electrolyte must be clearly above the level of the
standard solution.
Fill in fresh bridge electrolyte for measurement.
For more than a
week
Remove the bridge electrolyte of the electrode, rinse the
electrode with deionized water and dab it dry with a clean
paper towel. Store the electrode in a dry place.
