Electrode Cleaning Recommendations
Contaminant Cleaning Solution Procedure
Salt build-up Deionized water Soak in 20% or weaker
Acetic Acid solution
for 1 minute. Rinse
thoroughly with DI
water.
Oil Warm water and
household detergent Clean with mild
detergent solution.
Rinse thoroughly with
DI water.
NOTE: Do not contact the membrane with the cleaning solution. Install a
new membrane after cleaning the electrode.
Membrane Cap Assembly Replacement
1.
The electrode should remain attached to the meter.
2. Carefully unscrew the membrane cap assembly, in a clockwise direction,
and remove it from the electrode.
3. Discard the used membrane cap assembly. It cannot be reused.
4. Rinse the electrode with deionized water or tap water to remove
electrolyte solution.
5. Moisten a Polishing Strip. Use the cloth to clean, polish, shine and/or
remove scratches from the cathode. Do not over polish the sensitive
gold cathode. The polishing step is not necessary when assembling a
new meter.
