Moisture Vapor Transfer Tester
W3/0120 Water Vapor Transmission Rate Tester is based on the gravimetric method, which is available for water vapor transmission rate test of flexible films and sheets. It is advanced with 12 test cups for different specimens.
Principle:
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.
Standards:
ISO 2528, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208
