Cup Method Water Vapor Permeability Tester Water Vapor Transmission Rate Test Machine Equipment
1. Use
This instrument is based on the cup method, which is professionally applicable to the water vapor transmission rate test of thin film specimens. Through the determination of water vapor transmittance to control and adjust the technical index of material, meet the different needs of application.
Cup Method Water Vapor Permeability Tester Water Vapor Transmission Rate Test Machine Equipment
2. Character
1. Gas cylinder lifting structure design and periodically weighing method to reduce system errors
2. Six distinct or equivalent specimens can be tested individually with independent test results at one operation.
3. Standard air velocity can effectively prevent the formation of moisture gradient.
4. Wide range and high-precision of automatic temperature and humidity control to support various combinations of non-standard test conditions
5. Convenient fast-access calibration ports for temperature and humidity.
6. The system is controlled by computer and test process is automatic.
7. The tast report could be saved and provided in multiple formats,including Excel, database,etc.
8. Reference film or standard weight for fast and accurate calibration
9. The instrument is equipped with USB port and Common data port for convenient input, output, and data transfer

Cup Method Water Vapor Permeability Tester Water Vapor Transmission Rate Test Machine Equipment3. 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. PP, PVC and PVDC | |
| Paper and Paper Board | 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 | |
