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 re-
sponse appropriately after regeneration, must be replaced by a
new one.
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.
