8.2 Conductivity

Electrode

Keep the conductivity probe clean. Rinse the probe twice,

and gently swirl it while you take readings. For best

accuracy, soak a dry probe for at least 5 to 10 minutes or

longer before calibration. Rinse the probe with de-ionized

water before storing. Never scratch the bands with a hard

substance. Do not strike the probe against any hard

surface.

Do not immerse the probe in oily solutions. Clean the

electrode thoroughly by stirring it in a mild detergent bath

or isopropyl alcohol. Wipe the probe with a soft tissue

paper. Rinse thoroughly in tap water and then in de-

ionized water. Recalibrate the meter after cleaning the

probe.

The conductivity probe (Order Part No. EC-

CONSEN91W/ 35608-50) which is included with your

meter features a removable probe guard to make

cleaning easy.

To remove probe guard:

Grip yellow probe guard and twist clockwise. The

locking notch will release.

Slide probe guard off end of probe.
