Coulometry, See Full Listing of With this in mind, if you are storing your pH probe in tap water or any other solution, then, during storage instead of contaminated KCl flushing out and fresh KCl going in, instead what you'll find is your storage solution (be it tap water or maybe pH4 solution) will be going into your probe instead. Firstly, you should make sure you always keep your pH electrode moist, the best solution to submerge the probe for long and short term storage is 4M Potassium Chloride Solution (KCl).
