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 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.
If the filling solution (electrolyte) is more than 2½ cm (1”) below the fill hole, add HI 7082 3.5M
KCl Electrolyte Solution.
