AUTO W806 Water Vapour Transmission Rate Tester
Manufactured by GBPI Testing Instruments
The AUTO W806 water vapour permeability tester has been meticulously designed and manufactured in accordance with the ASTM E96 standard. It is based on the cup method to measure the water transmission rate of films, paper, sheets, fabrics, non-woven fabrics, and other related materials in various environments.
While this test is commonly used in the packaging industry, it’s also ideal for food, pharmaceuticals, daily chemicals, and medical devices.
