W3/030 Mositure Barrier Testing Machine is based on the cup method to measure water vapor transmission rate measurement of plastic films, laminated films, sheets as well as various materials used in medical and construction industries.

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

The test can be performanced as follows:

  •   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.
