Product Details
Test Principle
The specimen is determined WVTR through a barrier film or sheet. During the gravimetric test, a cup or dish is filled with desiccant or water, placed in a chamber with controlled temperature and humidity. By periodically measuring the weight change of the test disc, parameters such as water vapor transmission rate can be obtained.
