4.2.16 Setup Page 15.0: Replatinisation Process
This setup page allows you to replatinise the probe and is only
applicable for 2-cell probes.
Replatinisation is the process of replacing the platinum on the
surfaces of the 2-cell conductivity probes that may flake or wear off
over time. The platinum on the surface of the probe is used to
increase the measuring surface area, resulting in decreased
population error. Should the cell constant of your conductivity probe
change by more than 50% from its typical value, it may be necessary
to replatinise the probe. Replatinisation is a relatively quick procedure
to perform, typically taking no more than 5 minutes. Although
replatinisation is not a long process, the replatinisation solution is
costly.
