Electrode
Maintenance and Replacement
•
Rinse the electrode thoroughly with distilled water after use.
•
Do not touch the platinum black coating on the sensor surface and
always keep it clean.
•
If there is a build-up of solids inside the sensor, remove carefully,
then recalibrate the tester.
•
If you do not use the tester for long periods, store the electrode
with tap water.
Replacing the Electrode
If the tester fails to calibrate or gives fluctuating readings, you should
consider replacing the electrode.
1. Twist the electrode collar counter clockwise, pull the electrode
away from the tester.
2. Align the slot on the new electrode, gently push the electrode into
the tester.
3. Twist the electrode collar clockwise until tight.

Preparation of Conductivity Standard Solutions
Place the analytical grade potassium chloride (KCl) in a beaker and
dry in an oven for about 3 hours at 105° C (221° F), then cool to room
temperature. Add the reagent to a 1 liter volumetric flask according
to the instructions in table below. Fill the distilled water to the mark,
mix the solution until the reagent is completely dissolved.
