Water Vapor Transmission Rate Tester, to determine the water vapor transmittance of textiles, non-woven fabrics, film materials, sheets, paper, paperboard and other materials.
Using cup method, at a certain temperature, the specific humidity difference is formed on both sides of the sample, then the water vapor passes through the sample in the permeable cup into the dry side. Through measuring the changing weight of the moisture permeable cup to obtain the water vapor transmittance and other parameters of the sample.
- The moisture permeable cup can be tested independently. The test process not only meets the standard requirement strictly, but also automates control completely.
- The improved mechanical structure ensures strictly the accuracy of the weighing process of the permeable cup, and at the same time, the embedded computer system platform is configured, and its technical advantages and user experience are far superior to those of the traditional single-chip computer technology.
- Equipped with the latest operating software, it has humanized operation interface and intelligent data processing function, at the same time, it also supports LystemTM laboratory data sharing systemto unify the management of test results and test reports.
