3. Rinse the electrode with distilled or deionized water and blot-dry it with clean tissue or filter paper.
Rinse the electrode again with your test solution if possible for the best result. Never rub the
sensor.
4. Insert the electrode into your sample solution and stir it for a few seconds in the solution to
remove potential air bubbles. Then wait for the stable reading and take the measurement.
5. After measurement, insert the electrode back into the storage cap and twist it on. If the water in
the cap is contaminated, rinse out the storage cap and fill in new deionized or distilled water.
How to Maintain the Electrode
1. Always rinse the electrode with distilled or deionized water before and after each test and
calibration.
2. Store the electrode in the storage cap filled with distilled or deionized water when not in use.
3. Keep the electrode connector clean and dry. Use cotton balls with isopropyl alcohol to clean if it
gets dirty and then blow-dry it. This is to prevent a potential short circuit, which will undermine the
electrode’s performance.
