Abstract
An apparatus for measuring and comparing the permeant transmission rate through film material on a moving conveyor, including a first and second chamber through which the film material is moved, a permeant supply to the first chamber and a permeant detector connected to the second chamber. A computer processor is connected to the detector to quantify the detected amounts of permeant and to compare the detected permeant amounts with similar amounts detected for a different material sample, and for determining the permeant transmission rate characteristics of the film material by such comparison.
