8L Lab Water Vapor Permeability Tester -HTZ C1

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, textile and many others.

Standard:

ISO 2528, ASTM E96, ASTM D1653, GB 1037, GB/T 16928, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003

Principles

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.
