MINIMUM AMOUNT OF TIME, INCLUDING DURING
INSTALLATION.
Use care to minimize the exposure of the sensor to air. A 3-5 minute
exposure to air may require 24 hours or longer cell recovery period before
the cell recovers to less than 0.5 ppm on an oxygen free sample gas. On
the other hand, if the air exposure is limited to less than 10 seconds, the
recovery time will be reduced to two hours, or less.
If exposure to air or other high oxygen concentration atmospheres is
anticipated, retrofit your instrument to use the Insta-Trace Micro-fuel Cell.

3.4.2 Insta-Trace Micro-fuel Cell
The Insta-Trace Micro-fuel Cell eliminates the long recovery
period associated with exposure of the cell to air. This cell is capable of
measuring below 1 ppm of oxygen within 15 minutes of installation. By
reducing the recovery time from several hours to just minutes, users will
no longer have to divert unanalyzed product or switch analyzers.
