Maintenance and cleaning
During operation, a small amount of reference electrolyte leaks through the
junction from the electrode into the test sample. If the level of reference
electrolyte becomes too low with time, refill it through the refilling opening.
Refilling the
reference
electrolyte
Refilling is very easy using a dropping bottle. Proceed as follows:
 Cut off the tip of the dropping bottle at a right angle until the opening in the
tip can be seen
 Open the refilling opening of the electrode
 Press the tip of the dropping bottle into the refilling opening while turning
it slightly
 Pump several small quantities of the reference electrolyte into the stem
using the dropper bottle
 Pull the dropping bottle out of the refilling opening while turning it slightly
as necessary.
