Care and Maintenance/Probe Maintenance:

The silver cathode should always be bright and untarnished. If it is tarnished or stained, the cathode should be cleaned gently witha lint-free cloth.
Rinse the probe with deionized or distilled water.
Replace the membrane cap using fresh electrolyte.
Recalibrate meter.

Membrane Maintenance:

For accurate and stable measurements, perfect condition of the membrane surface is needed. Protect the thin membrane from scratches, abrasion or contact with solids.
If no measurements are taken for a few hours, protect the membrane with the plastic protective cap.
If fouled, rinse it carefully with distilled or deionized water. If damaged, replace the membrane cap.
Note: Change the membrane every 8 weeks or more frequently if used in a specially fouling environment. Check and replace the electrolyte fill solution every 4 weeks.


After taking measurements, switch the meter off and clean the probe before storage. When not in use the probe should be stored with the plastic cap on.
For short term storage, the probe can also be stored in a beaker of deionized water with the protective plastic cap removed.

For long term storage, the probe should be stored dry:

1. Disconnet the probe from the meter.

2. Unscrew the membrane cap.

3. Remove any electrolyte solution from the cap.

4. Rinse the probe anode/cathode assembly with distilleed water and blot dry.

5. Screw the membrane cap onto the probe until the membrane cap is hand tight.
