STORAGE PROCEDURE

To minimize clogging and assure a quick response time, the glass bulb and the junction of the

electrode should be kept moist and not allowed to dry out.

Replace the solution in the protective cap with a few drops of HI 70300 Storage Solution or, in

its absence, with HI 7082 Fill Solution. Follow the Preparation Procedure before taking

measurements.

Note: NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED WATER.

PERIODIC MAINTENANCE

Inspect the electrode and the cable. The cable used for connection to the instrument must be

intact and there must be no points of broken insulation on the cable or cracks on the electrode

stem or bulb. Connectors must be perfectly clean and dry. If any scratches or cracks are present,

replace the electrode. Rinse off any salt deposits with water.

PROBE MAINTENANCE

Refill the reference chamber with fresh electrolyte (HI 7082). Allow the electrode to stand

upright for 1 hour. Follow the Storage Procedure above.
