Maintenance and cleaning
During operation, a small amount of reference electrolyte leaks through the
junction from the combination electrode into the test sample. If the level of
reference electrolyte becomes too low with time, refill it through the refilling
opening.
Refilling reference
electrolyte
Refilling is very easy using a dropper bottle. To do so, 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 combination electrode
 Press the tip of the dropper 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 dropper bottle out of the refilling opening while turning it slightly if
necessary.
