WVTR-W6 WVTR Permeability Tester Water Vapor Transmission Rate Tester
(Gravimetric Method)
(Gravimetric Method)
WVTR-W6 WVTR Permeability Tester Water Vapor Transmission Rate Tester, based on the Gravimetric method, provide a wide range and high efficiency water vapor transmission rate testing experience for low, medium and high water vapor barrier materials. It is suitable for the measurement of water vapor transmission rate of various materials such as plastic film, composite film, medical treatment, construction, etc. By testing the water vapor transmission rate, the technical index of the materials could be controlled to meet the requirements for production.
Product Features
Advanced Technology

- Pubtester also provides professional customization services to meet users' personalized needs in fixtures, software, etc.
- Provide lifetime software free upgrade
Based on gravimetric determination method, under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.
Applications
| Basic application | Film | Plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminum coated films, aluminum foil composite films, glass fiber aluminum foil paper composite films and many other film materials |
| Sheeting | PP, PVC and PVDC sheeting, metal foils, rubber pads and other sheeting materials | |
| Textiles and Non-woven | Textiles and non-woven fabrics such as diaper, sanitation products, etc. | |
| Paper and Paper Board | Aluminum coated paper for cigarette, paper aluminum plastic composite film and other paper and paper boards | |
| Extended application | 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 | |
| Cosmetic | Water vapor permeability of cosmetics | |
| Aseptic Films | Aseptic wound protecting films, medical plasters and protective clothing materials | |
| LCD Display | Water vapor transmission rate of LCD display and its relevant sheet | |
| Solar Back-sheets | Water vapor transmission rate of solar Back-sheets and its relevant sheet | |
| Paint Film | All types of paint films | |
| Biodegradable Films | Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films |
