Storage
The connector should be protected from hu-
midity by the protective cap
Place the electrode in the storage protector
with Crisolyt (KCl 3M).
Close the refilling port with the stopper
Life of an electrode
The average life expectancy of a pH electrode
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.
To avoid accidental breakage of the glass body
electrodes, the use of the working protector,
code 91 62, is recommended.
If an electrode has too short life span,
less than three months, ask us about it.
Probably there is a more suitable electrode
for the application.
