Replatinization
XL20, 30, 50 and 60 meters
Replatinization 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 surface area of the measuring surface resulting in decreased polarization error.
Replatinization is a relatively quick procedure to perform, 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 1-888-358-4706.
To Perform Replatinization
1. Access the Replatinization mode from the Mode screen. In any measuring mode, touch
Mode
to access the Mode screen.
2. Touch
Replat.
to enter the Replatinization mode.
3. Immerse your 2 cell conductivity probe into the replatinization solution. The immersion
depth should be enough to cover the vent holes on the probe.
4. Touch
Start
on the display screen to begin the process of replatinization. At this time a
countdown timer will appear on the display screen showing the time elapse and time
remaining in the replatinization procedure.
Note:
At anytime after you have initiated the replatinization:
You can touch
Stop
to stop the procedure
OR
You can touch
Exit
to cancel the replatinization the procedure and return to the Mode screen.
4-cell conductivity probes do not require replatinization.
