Possible salt deposits in the area of the watering cap do not affect the measuring characteristics and can easily be removed with deionized water. Note Please keep the watering cap. It is required for the electrode to be stored. Always keep the watering cap clean.
SensoLyt® WQL Aging Storage During short measuring breaks Immerse the electrode in reference electrolyte (KCl 3 mol/L, Ag+ free). Prior to the next measurement, shortly rinse the electrode with the test sample or deionized water. Overnight or longer For prolonged storage we recommend to keep the electrode installed in the logger. Put the clean electrode in the watering cap that is filled with reference electrolyte (KCl 3 mol/L, Ag+ free).
