CARE AND USE

Probe Maintenance: The silver cathode should always be bright and untarnished. If it is tarnished or stained, the cathode should be cleaned gently with a lint-free cloth following these steps:

Rinse the probe with deionized or distilled water.
Replace the membrane cap using fresh electrolyte.
Recalibrate the meter.

Membrane Maintenance: For accurate and stable measurements, the membrane surface needs to be in perfect condition. Protect the thin membrane from scratches, abrasions or contact with solids by following these steps:

If no measurements are taken for a few hours, cover the membrane with the plastic protective cap.
If fouled, rinse 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 an especially fouling environment. Check and replace the electrolyte fill solution every 4 weeks.

Storage: 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 following these steps:

Disconnect the probe from the meter.
Unscrew the membrane cap.
Remove any electrolyte solution from the cap.
Rinse the probe anode/cathode assembly with distilled water and blot dry.
Screw the membrane cap onto the probe until the membrane cap is hand tight.
