Water Vapor Transmission Tester - 16 Test Dish

Application:

Water Vapor Transmission Tester determines the permeation of water vapor transfer through test specimen, it's applicable to various materials, such as plastic film, paper, sheet materials, fiberboards, gypsum, wood products and plaster products, etc.

 

Principle:

Seal the test specimen over the open mouth of one of the test dish of which contains water; then place the assembly in controlled atmophere of Water Vapor Transmission Tester. After a period of water vapour pressure across the test specimen, the assembled dish will have successive weighings, and the machine will determines the water vapour permeation.
