3.2 Measurement Procedures

Dipping sensor into liquid

To help avoid errors due to air bubbles around the sensor element (inner electrode),
immerse the sensor into the liquid to be measured so that its air vent is below liquid
level. To dislodge any air bubbles from the inner electrode, dip the sensor into the liquid
and move it up and down two or three times.
