11.5 Maintenance

To maximize the lifetime of the pH probe it is very important to make sure the probe is always in
contact with the storage buffer solution when not in use. The probe shall always be placed in the
holder and the tip of the probe shall be covered by the storage buffer solution. Be especially care-
ful that the storage buffer solution does not dry out when the probe is stored for a long time, and
please regularly check that the probe is covered by the storage buffer solution.
Even when making sure the probe is always kept in contact with the storage buffer solution, the
pH probe will still wear out over time due to clogging of the small pores in the tip of the probe. I.e.
the pH probe has a limited lifetime – even with careful maintenance – and one should expect to
replace the probe regularly. The typical lifetime for a well-maintained pH probe is 2 years.
When the pH measurement takes a long time to stabilize then the probe is defective and needs to
be replaced. A replacement pH probe can be purchased from Cortex Technology by contacting
cortex@cortex.dk or your local Cortex distributor.
