Replacement of the pre-membraned cap is required
when you cannot calibrate the probe, or if the
membrane is damaged. Typical membrane
damages are punctures or wrinkles caused during
measurements or cleaning:-
1) Unscrew counter clockwise the cap from the
probe sensing tip.
2) Wash the probe under running water.
3) Take the refill solution and assemble the
needle tip on the tip of the plastic bottle.
4) Hold the probe upside down.
5) Insert the needle into one of the four holes
surrounding the silver cathode.
6) Inject the fill solution into the probe until
solution leaks out of the fill hole (± 5 mL).
7) Replace the cap by tightening clockwise until
hand tightened.
8) Allow at least 1 hour for the electrode to
equilibrate before usage.
Note: The electrolyte solution in the probe depletes
on usage and needs to be replaced periodically.
