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.

If the filling solution (electrolyte) is more than 2½ cm (1”) below the fill hole, add
HI 7082
or
HI 8082
3.5M
KCl Electrolyte Solution for double junction or
HI 7071
or
HI 8071
3.5M KCl+AgCl Electrolyte Solution for
single junction electrodes.
For faster response, unscrew the fill hole screw during measurements.
