Crison 53 03 Mode D'emploi page 11

Storage
The connector should be protected from hu-
midity by the protective cap
Place the electrode in the storage protector
with Crisolyt (KCl 3M).
Life of an electrode
The average life expectancy of a pH process
electrode oscillates between 6 or 12 months,
depending on the working conditions.
Electrodes exposed to high temperatures do
not last as long. Very alkaline mediums also
reduces the life span of electrodes.
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.
