PREPARATION PROCEDURE
Remove the protective cap of the ORP elec-
trode (MA924B/1).
DO NOT BE ALARMED IF SALT DEPOSITS

trodes. 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 elec-
trode as you would do with a glass
thermometer.
If the bulb and/or junction is dry, soak the
electrode in MA9015 Storage Solution for at
least one hour.
If the filling solution (electrolyte) is more
