PREPARATION PROCEDURE

Remove the electrode protective cap.

DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is normal

with electrodes and they will disappear when rinsed with water.

During transport tiny bubbles of air may have formed inside the glass bulb.

The electrode cannot function properly under these conditions. These bubbles

can be removed by "shaking down" the electrode as you would do with a glass

thermometer.

If the bulb and/or junction are dry, soak the electrode in HI 70300 Storage

Solution for at least one hour. Open the fill hole if refillable.

Not present in gel electrodes.
