Conductivity Electrode’s Maintenance
4.8.1.
Always keep the conductivity electrode clean. Before taking a measurement, rinse the electrode in
pure water. It is recommended to rinse it again in the sample solution. When submerge the electrode in
solution, stir the solution briefly to eliminate air bubbles and allow it to stay until a stable reading is reached.
Conductivity electrodes are usually stored dry. For conductivity electrodes that haven’t been used for a
long period, users should soak the electrode in 12.88 mS calibration solution for 5-10 minutes, or to soak
it in tap water for 30 minutes to an hour. Rinse the electrode in pure water after conditioning.
4.8.2.
The sensing rod of 35419-32 conductivity electrode is coated with platinum black to minimize
electrode polarization and expand measuring range. The platinum black coating adopted our special
processing technology, which improves the electrode performance and the firmness of the coating. If the
platinum black electrode is stained, gently clean the electrode with soft brush in warm water containing
detergent or alcohol.
