8 CONDUCTIVITY OPERATION
8.1 Replatinization
Replatinization is the process of replacing the 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. Replatinization is a
relatively quick procedure to perform, typically taking no more than
5 minutes. Although replatinization is not a long process,, the
replatinization solution is costly. If you are not certain that
replatinization will improve the performance of your accumet
conductivity probe, please call the technical support hotline at
800/943-2006, or 412/ 490-6260.
1. Immerse the probe into a suitable replatinizing solution.
2. From the Measure Screen, press setup and enter together to
access the replatinization mode. 5.00 minutes will appear on
the main display.
MIN
3. Press enter to initiate replatinization. The timer will countdown
from 5.00 minutes on the main display. Upon completion, the
meter will return to the Measure screen. Repeat step 2 if a
longer replatinization is required.
4. A new cell constant must now be established for the
probe. Refer to the standardization section, page .
