PREPARATION PROCEDURE
Remove the protective cap of the ORP electrode (
HI 3148B).
DO NOT BE ALARMED IF SALT DEPOSITS ARE PRESENT. This is normal with electrodes. They will
disappear when rinsed with distilled/deionized water.
During transport, tiny bubbles of air may have formed 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.
