Maintenance
Cleaning
To ensure accurate and reproducible results, the electrode cell must be clean.
A dirty cell will contaminate the solution and change the conductivity of the
liquid.
Cells can be cleaned with detergent and/or dilute nitric acid (1%) by dipping
or filling the cell with cleaning solution and stirring for three minutes.
Storage
Although the best method to store the electrode is by immersing it in deionized
water, the electrode can be stored dry in its container. If the cell is stored dry,
it should be soaked in distilled water for 5 to 10 minutes before use.
