WVTR Test System Supplier
WVTR Test System Supplier
Product Code : W3/060
Brand Name : Labthink
Product Description
W3/060 WVTR Test System Supplier   is based on the gravimetric method to determine the WVTR of flexible films, sheets and foils. It is advaced with 6 test cups for 6 different specimens.


Under a certain test temperature, 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. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.


ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208
