EXTENDED APPLICATIONS

• Inverted cup method:
  Mount the film or sheet on the test plate, cover the top surface of the sample with distilled water and make the bottom in certain humidity. Generate a constant humidity difference. between two sides; Water vapor penetrates through the sample and measure the weight changes at different times to obtain the water vapor transmission rate.
  NOTE: Inverted cups required
• Artificial Skin:
  Artificial skin has to meet standard requirements for water Vapor transmission rate to ensure better respiratory performance. This instrument can be used to test water vapor permeability.
  artificial skin
