ISO 2528 Water Vapor Permeability Tester Cup Method Test Water Vapor Transmission Rate
1. Use
This instrument is based on the cup-shaped method and is specifically designed for testing the water vapor transmission rate of film samples. The technical indicators of materials are controlled and regulated by measuring the water vapor transmission rate to meet different application requirements.
2. Character
1. The design of the gas cylinder lifting structure and the periodic weighing method reduce systematic errors
2. In one operation, six different or equivalent samples can be tested separately and independent test results can be obtained.
3. The standard wind speed can effectively prevent the formation of the water vapor gradient.
4. Wide-range and high-precision automatic temperature and humidity control, supporting various combinations of non-standard test conditions
5. Convenient and quick access to the temperature and humidity of the calibration port.
6. The system is controlled by a computer and the testing process is automated.
7. The final report can be saved and provided in multiple formats, including Excel, database, etc.
8. Quick and accurate calibration with reference membranes or standard weights
9. The instrument is equipped with USB port and Common data port for convenient input, output, and data transfer

3. 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 | |
| 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 |
