Water Vapor Transmission Tester

Determine the value of water vapor transfer through permeable and semipermeable materials.

Product Model: YG216-I
Design Standard: ASTM E96, JIS L1099, BS 7209

Application:

Water Vapor Transmission Tester determines the value of water vapor transmission (WVT) of materials, such as paper, plastic film, sheet materials, fiberboards, wood products and plastics. It's limited to test specimens not over 32mm in thickness.

 

Test Method:

Water Vapor Transmission Tester adopts Water Method:

Test dish contains distilled water, and the weighings determine the rate of vapor movement through test specimen from water to the controlled atmosphere.
