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.
If an electrode has too short lifespan, less than three months,
ask us about it. Probably there is a more suitable electrode for the
application.
