    Due to the additional volume added by the coalescing filter, there is an exception to the Response Time specification for the 480L: when equipped with the Sample Conditioner option, a 480L instrument’s Response Time is <60 seconds to 95%.

  • Page 28: Permeation Gas Dryer Option

    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.
