electrode material for internal reference electrode comprising a cation, a solution of an internal reference, as well as the cation sensitive membrane.the electrode is characterized in that the internal reference solution containing a saturated solution of a salt of a cation other than the cation sensitive membrane, which is mainly the internal reference solution selectively, is formed in situ by the hydration of a combined reason of salt of the cation with a hygroscopic material.by absorption of water from the atmosphere and / or by hydration of the hygroscopic material in the electrode works, forming the internal reference solution.
