Water Vapor Permeability Tester

Water vapor permeability is a measure of the passage of water vapor through the material. It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR). It is the mass of water vapor transmitted through a unit area in a unit time under specified conditions of temperature and humidity.

Water vapor permeability tester conforms to the multiple national and international standards:
