3. Remove the membrane cap assembly from the probe.
4. Rinse the anode, cathode, and membrane cap assembly
with water.
5. Shake the water out of the membrane cap.
6. Use a clean lab wipe to blot the moisture from the electrode
anode and cathode.
7. Thread the membrane cap assembly loosely onto the body of
the probe.
8. Replace the membrane protector on the membrane cap.
3.4.5 Maintenance
Membrane cap replacement and refilling are required at
scheduled intervals or whenever the membrane has been damaged
or fouled. If the membrane is not damaged or fouled, the
recommended time interval for replacing the electrolyte filling
solution is 1-2 months.
Prior to replacing a membrane cap, rub the anode (the outer
metallic stem of the probe that is visible when the membrane cap
is removed) with the polishing cloth supplied with the probe. The
polishing cloth will remove deposits that may decrease the
performance of the probe. Polish the anode whenever the
membrane cap is replaced or between membrane cap replacement
if probe performance seems to have degraded over time.
