Water Vapor Permeability Device

Product Information
W3/030 Water Vapor Transmission Rate Tester is based on the cup method and can be professionally used in determining the water vapor transmission rate of plastic films, composite films, sheets and other materials used in the medical industry and construction industry. By testing the water vapor transmission rate, the technical index of materials can be controlled to meet production requirements.

Testing Principles:
At a certain test temperature, a constant humidity difference occurs on the two sides of the test sample. Water vapor passes through the sample towards the dry side. By measuring weight changes in the test vessel at different times, water vapor transmission rate and other parameters can be obtained.
