PREPARATION

Remove the protective cap.
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 shak-

ing down the electrode as you would do with a glass thermometer.
If the bulb and/or junction is dry condition the electrode by soaking it in
HI 70300 or HI 80300

storage solution for at least one hour.
