ELECTRODE CONDITIONING
AND MAINTENANCE
PREPARATION PROCEDURE
Remove the protective cap.
DO NOT BE ALARMED IF 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
storage solution for at least one hour.
Note: To prevent damage to the electrode, remove the pH
electrode from the solution before turning the meter off.
If the meter is OFF, detach the electrode from the meter
before immersing the electrode in the storage solution.
