Lidding films are used because of their good water vapor barrier property and can protect the food from water vapor in the air. Labthink TSY-W3/3 water vapor permeation and barrier testing instrument is applicable to the determination of water vapor transmission rate of plastic films, composite films, high barrier materials, back-sheets, sheeting, building thermal insulation materials, waterproof materials, packages and other materials used in sanitary and medical industry.
This water vapor permeation and barrier testing instrument is controlled by micro-computer with LCD, menu interface and PVC operation panel, which could conveniently export test data, test results and test curves.
3 distinct or equivalent specimens could be tested simultaneously with individual test results.
