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:
1.
Grip yellow probe guard and twist clockwise. The
locking notch will release.
