What should the pH or ORP level of the storage solution be?
You will not be able to get an accurate read on the storage solution, since there may not be enough, there is a sponge in the cap, and the solution value will quickly become corrupted by other liquids. You should not attempt to calibrate to the storage solution. The sole purpose of the storage solution is to keep the electrodes saturated. For calibration, always use a laboratory-certified pH or ORP buffer.
