Storage
Place the electrode in the storage protector
electrolyte (Crisolyt A, KCl 3M sat. AgCl).
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 regeneration, 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 lifespan, less than three months,
ask us about it. Probably there are more suitable electrode for the
application.
