ISO2528 ASTME96 D1653 Water Vapor Permeability Tester Steam
Penetration Rate Testing Machine
Instroduction
The water vapor permeability tester can measure the water vapor
permeability of various materials under various conditions. The
test conditions can simulate the actual application environment.
The experimental results are accurate and reproducible.
Compliant with standards
GB1037,YBB00092003,ASTME96,GB/T17146,GB/T16928,YYT0471.2,ASTMD1653,ISO2528,DIN53122-1,JISZ0208,TAPPIT464
Operating principle
At the required temperature, two separate air streams remain on
both sides of the sample. Measure the humidity and gas flow rate.
Use mass balance to calculate the transmission rate through the
sample.
Technical Features
1. The required humidity can be maintained on either side of the
sample.
2. Any desired pressure gradient can be achieved.
3. Any required test temperature can be obtained.
4. The pressure box humidity gradient can be simultaneously
restricted.
5. Flat samples of any size can be used.
6. The test can be fully automated, including execution, data
acquisition, data storage, and data simplification.
Product Application
The water vapor permeability tester can measure the water vapor
permeability of porous materials (such as: textiles, leather,
artificial materials, films, non-woven fabrics, and fabrics used in
many high-tech components as well as many industrial manufactured
consumer goods). This instrument has the unique ability to measure
the water vapor permeability under a wide range of conditions
encountered in application environments, including humidity,
humidity gradients, temperature, and pressure.
Application Industries: Filtration/Films, Textiles/Latex, Household
& Personal, Non-woven Fabrics, Food Packaging, Hygiene.
