Paper and Paper Board Water Vapor Transmission Rate Instrument
Labthink manufactures and exports Professional, High Efficiency and Intelligent Water Vapor Permeability Tester, which is based on the cup method, and is professionally applicable
to the water vapor permeability test of film specimens.
Principle
Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into
the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained
