WebA deliberate salt residue is often placed around the probe as a protective shipping solution so what you may be seeing is normal. Before calibration, rinse the salt off and let the …
WebElectrodes. The best way to store the pH sensing electrodes during non-use is to fill the electrode protective cap about half-way with storage solution , then put the cap on the electrode making sure the cover is tight. Check the electrode periodically to ensure solution has not evaporated. If evaporation occurs, refill the cap or beakers/cups. WebMaintenance of pH Meter Electrode (from Cole-Parmer, Manufacturers) ... Air Bubbles: If air bubbles appear in the electrode (especially with microelectrode and narrow test tube electrodes), open up the fill hole, grab the cable of the probe about 18" from the connection to the electrode, and spin in a circular motion over your head (like a ...
WebLeaving electrodes dirty. pH testing can be a dirty business. Sticking the electrode in hot milk, fermenting wine, or wet soil can cause buildup on the surface of the electrode that is undetectable to the eye. Fats, sugars, or minerals can accumulate on the electrode resulting in slower or even faulty readings.
Web8. Fill the electrode with the fill solution that is in the box to a level just below the fill hole. NOTE: When the electrode is in use the fill hole must be open. 9. Ensure that there are no air bubbles in the electrode liquid.
