Test principle
Using the test principle of weighing method of permeable cup, a specific humidity difference is formed on both sides of the sample at a certain temperature, and the water vapor enters the dry side through the sample in the permeable cup. By measuring the change of the weight of the permeable cup with time, the water vapor transmittance of the sample is obtained.

Applications Specifications
Basic Applications | Films | Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others |
Sheeting | Including engineering plastics, rubber and building materials, e.g. עמ', PVC and PVDC | |
Paper and PaperBoard | Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials | |
Textiles and Nonwovens | Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products |
Extended Applications | Inverted Cup Method | Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cups are required |
Artificial Skin | Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test water vapor permeability of artificial skin | |
Medical Products and Accessories | Including plasters, aseptic wound protecting films, face masks and scar sticks | |
Solar Back-Sheets | Including solar back-sheets | |
LCD Monitor Films | Including LCD monitor films | |
Paint Films | Test water vapor permeability of various sorts of paint films | |
Cosmetics | Test water vapor permeability of cosmetics | |
Biodegradable Films | Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films |
