3.5.4 PERMEATION GAS DRYER OPTION
The Permeation Gas Dryer serves to remove water vapor from sampling gas in a
humid environment. It is an alternative option when there is no risk of condensation.
The permeation material is a Teflon™-type compound and has only a minimal
effect on the ozone concentration in the sample stream. When the 480L is equipped
with this option, the unit has been calibrated at the factory to compensate for any
ozone loss in the permeation dryer.
