To ensure a quick response and free-flowing junction, the sensing
element and reference junction must not dry out. Always clean the
electrode before storing it.
Short-term storage (up to one week): Soak the electrode in pH
electrode storage solution, Cat. No. 910001. To prevent crystallization
of the filling solution, cover the fill hole whenever the electrode is being
stored and open the fill hole when calibrating and measuring.
Long-term storage (more than one week): Fill the electrode
and securely cover the filling hole. Cover the electrode with the
protective glass tube containing a few drops of storage solution. Before
returning the electrode to use, prepare it as a new electrode.
