Product Description:

Principle of  XHF-87 Water Vapour Permeability Tester

The sample is fixed on the opening of a test bottle containing a certain amount of solid desiccant. In a conditioned environment, the test bottle was placed in a strong air stream in the rotation test bottle, the bottle let the desiccant in constant motion, the test bottle was weighed after rotation, the sample is measured the mass of the desiccant absorbing water vapor.
