Life of an electrode
The average life expectancy of a pH proc-
ess electrode oscillates between 6 or 12
months, depending on the working con-
ditions.
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 elec-
trode for the application.
