PREPARATION PROCEDURE
Remove the protective cap of the pH electrode.
DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal
with electrodes. They will disappear when rinsed with water.
During transport, tiny bubbles of air may form inside the glass bulb affect‑
ing 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
HI70300
or
HI80300
Storage Solution for at least one hour.
