Water Vapor Permeability Device

The W3 / 030 Water Vapor Transmission Rate Tester is based on the container method and can be used professionally to determine the water vapor transmission rates of plastic films, composite films, sheets and other materials used in the medical and construction industries. By testing the water vapor transmission rate, the technical index of the materials can be checked to meet production requirements.
Test Principles:
At a certain test temperature, a constant humidity difference occurs on both sides of the test sample. Water vapor passes through the sample to the dry side. By measuring the weight changes in the test vessel at different times, the water vapor transmission rate and other parameters can be obtained.
Standards:
ISO 2528, GB 1037, GB/T 16928, ASTM E96, ASTM D1653, TAPPI T464, DIN 53122-1, JIS Z0208, YBB 00092003
