The electrodes should not be stored in distilled water. The filling solution will be diluted and the electrode response will be slow. If using a refillable pH electrode, the fill hole should be covered overnight and during storage. The fill hole cover must be removed during calibration and measurement to ensure a uniform flow of electrode filling solution. The best way to store the electrode is to read the included manual. We also carry an Electrode Storage Solution at our eBay Store! Maintenance and cleaning: The electrode should be inspected weekly for scratches, cracks, or salt cry
