ELECTRODE CONDITIONING

& MAINTENANCE

PREPARATION

Remove the 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 form inside the glass bulb

affecting proper functioning of the electrode. These bubbles can be

removed by "shaking down" the electrode as you would do with a

glass thermometer.

If the bulb and/or junction is dry, soak the electrode in HI 70300 or

HI 80300 Storage Solution for at least one hour.
