Application
WVTR-C1 is based on the weighing method and available for the water vapor permeability
test of plastic films, aluminum foil, aluminized films, plastic composite films
Test dishes filled with distilled water in a controlled dry atmosphere, a constant humidity
difference is generated between two sides of the test specimen, the water vapor permeates
through the specimen and into the dry side, water vapor transmission rate and other
parameters can be obtained by measuring the weight changes of the test dish in different
time.
