  WVTR-W6 Water Vapor Transmission Rate Tester The WVTR-W6 Water Vapor Transmission Rate Testing System provides high-efficiency water vapor transmission rate testing through fully automatic weight measurement of 6 samples simultaneously, based on the cup method (gravimetric method), across a wide testing range for low, medium, and high water vapor barrier materials. It is suitable for measuring the water vapor transmission rates of various materials, including plastic films, composite films, medical applications, and construction materials. By efficiently testing the water vapor transmission rate, it enables control of the technical indicators of materials and allows for meeting production requirements at a low cost.
