About This Product
Water vapour permeability is the ability of leather to let moisture pass through it, which matters for leather used in apparel. In this test a circular specimen is clamped over the mouth of a bottle holding a solid desiccant, and a rapid current of air is passed over it. The desiccant is kept moving so that the air inside the bottle circulates. The gain in weight of the bottle over a set time measures the permeability.
Frequently Asked Questions
Q1. What does the Water Vapour Permeability Tester measure?
It evaluates the water vapour permeability of leather, that is, its ability to allow moisture to pass through it.
Q2. How is the result obtained?
The increase in weight of the bottle over a specified interval of time gives the quantitative measure of the water vapour permeability of the leather sample.
