Storage
The connector should be protected from
humidity by the protective cap
Place the electrode in the storage protec-
tor with KCl 3M.
Close the refilling port with the stopper
Life of an electrode
The average life expectancy of a pH elec-
trode is approximately one year depending
on the working conditions.
An electrode used for more than six months
that does not response appropriately after re-
generation, must be replaced by a new one.
If an electrode has too short lifespan,
less than three months, ask us about it.
Probably there is a more suitable elec-
trode for the application.
