Water Vapor Transmission Rate (WVTR) Tester / Water Vapor Permeability Tester | 572-CT
Toyo Seiki · Permeability / Gas Transmission Rate / Water Vapour Transmission Rate
The Water Vapor Transmission Rate (WVTR) Tester measures the water vapor permeability or water vapor permeability coefficient of packaging materials such as plastic film. Measures water vapor permeability and water vapor permeability coefficient of plastic films, etc. using the differential pressure method.
