Conductivity Electrode Care
The conductivity electrode needs to be
kept clean and free of deposits and other
types of build-up. Use the detergent
powder supplied in the plastic bag for
cleaning the electrode.
1. Mix a convenient amount of
cleaning solution using the detergent
powder. Use a mixing ratio that is
30 grams of powder to 4 liters of
water (the bag contains 30 grams).
2. Dip the brush into the cleaning
solution.
3. Insert the brush into the conductivity
electrode approximately 1
1
⁄
2
” taking
care to clean both conductance
rings. One ring is located at the
bottom of the electrode and the
other is located approximately 1” up
from the bottom, above the blue
collar.
4. Twist the brush and scrub up and
down for 20 to 30 seconds.
5. Rinse the electrode thoroughly in
distilled or deionized water.
6. Clean the brush with tap water and
rinse it with distilled or deionized
water after using.

Replacement
THE CONDUCTIVITY ELECTRODE
CANNOT BE UNSCREWED (THIS IS
THE ELECTRODE WITH A SMALL
HOLE IN THE BLUE CONNECTOR
HOUSING). The conductivity electrode
is field replaceable by qualified
technicians only. The part number of the
conductivity electrode is CDE-8200.
Contact NEWPORT’s Engineering
Department for instructions on how to
replace the electrode.
