Cap and Electrolyte Replacement
Replacement of the pre-assembled cap is required only when you cannot
calibrate the probe, or if the membrane is damaged. Typical membrane
damages are punctures or wrinkles caused during measurements or cleaning.
For part numbers, see Section 11 – REPLACEMENTS AND ACCESSORIES.
1) Unscrew the cap counter clockwise from the probe sensing tip.
2) Rinse the probe under running water.
3) Mount the nozzle tip onto the syringe provided. Fill the syringe with the
refill solution through the tip of the plastic bottle.
4) Hold the probe upside down. Insert the nozzle tip into one of the 4 holes
surrounding the silver cathode. Inject the fill solution into the probe body
until solution leaks out from the fill hole (approximately 5 mL).
5) Replace pre-assembled cap by tightening clockwise until hand tightened.
6) Allow at least 1 hour for the electrode to equilibrate before usage.
