ELECTRODE CONDITIONING & MAINTENANCE
PREPARATION PROCEDURE PREPARATION PROCEDURE PREPARATION PROCEDURE PREPARATION PROCEDURE PREPARATION PROCEDURE
Remove the electrode protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal with
electrodes and they will disappear when rinsed with water.
During transport tiny bubbles of air may have formed inside the glass bulb. The electrode
cannot function properly under these conditions. These bubbles can be removed by
“shaking down” the electrode as you would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in MA 9015
MA 9015
MA 9015 MA 9015
MA 9015 storage solution for
at least one hour.
For refillable electrodes, if the refill solution (electrolyte) is more than 2½ cm (1”) below
the fill hole, add the appropriate electrolyte solution.
MEASUREMENT MEASUREMENT
MEASUREMENT MEASUREMENT MEASUREMENT
Rinse the electrode tip with distilled water, immerse it (4 cm / 1½") into 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 the solution to be tested before taking any measurements.

STORAGE PROCEDURE
To minimize clogging and ensure a quick response time, the glass bulb and the junction
should always be kept moist.
When not in use, store it with a few drops of M

PERIODIC MAINTENANCE
Inspect electrode and cable. The cable used for the 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. If any scratches or cracks are present, replace the electrode.
Rinse off any salt deposits with water.
Connectors must be perfectly clean and dry.
For refillable electrodes:
Refill the electrode with fresh electrolyte (see the electrode’s specifications to select the
correct refilling solution). Allow the electrode to stand upright for 1 hour. Follow the
Storage Procedure above.
