PREPARATION PROCEDURE

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
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.
