electrodes:

If the electrode does not respond to pH changes, the battery may have run down and the electrode
or battery (if replaceable) should be replaced.

MEASURE

Rinse the pH electrode tip with distilled water. Immerse the tip bottom 4 cm (1.5”) in the sample
and stir gently for a few seconds.
For a faster response and to avoid cross-contamination of the samples, rinse the electrode tip with
a few drops of the solution to be tested, before taking measurements.

STORAGE PROCEDURE

To minimize clogging and ensure a quick response time, the glass bulb and the junction of pH
electrode should be kept moist and not allowed to dry out.
Replace the solution in the protective cap with a few drops of

HI70300

or

HI80300

Storage

Solution or, in its absence, Filling Solution (

HI7071

or

HI8071

for single junction and

HI7082

or

HI8082

for double junction electrodes). 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.

pH PROBE MAINTENANCE

For refillable electrodes:

Refill the reference chamber with fresh electrolyte (

HI7071

or

HI8071

for single junction or

HI7082

or

HI8082

for double junction electrodes). Allow the electrode to stand upright for 1 hour.

Follow the Storage Procedure above.

pH CLEANING PROCEDURE

•

General

Soak in Hanna Instruments

HI7061

or

HI8061

General Cleaning Solution for

approximately 30 minutes.

•

Protein

Soak in Hanna

Instruments

HI7073

Protein Cleaning Solution for 15 minutes.

•

Inorganic

Soak in Hanna Instruments

HI7074

Inorganic Cleaning Solution for 15 minutes.

This is good at cleaning a black ceramic junction.

•

Oil/grease

Rinse with Hanna Instruments

HI7077

or

HI8077

Oil and Fat Cleaning Solution.
