Water Vapor Permeability Tester is suitable for testing the water vapor transmission performance of textiles and textile composites (especially sportswear fabrics). It meet with BS 3424 BS 7209 standard.

Water Vapor Permeability Tester YG501S

Water Vapor Permeability Tester is equipped with eight test container and the standard vapor permeability fabric cover, sample holder ring and precision drive system.

In a constant temperature and humidity environment, the sample covers on a sample vessel containing water. After a certain period of time, water vapor permeates from the fixed area of sample. The weight of water vapor passing through was weighed to calculate the water vapor transmission rate and the water vapor transmission index.

Follows are Water Vapor Permeability Tester Specification :

  • Large aluminum turntable with anodized surface, flat and wear-resistant;
  • One-piece processed and molded test vessel with built-in water line for more convenient water control;
  • Synchronous belt drive mechanism with simple structure, away from the test area to prevent heat conduction
  • Highlighted LED digital display test time;
  • Circulation ventilation system can cool the instrument when it is running for a long time.


Application of Water Vapor Permeability Tester

Water Vapor Permeability Tester is used to measure the ability of water vapor to pass through the fabric by hygroscopic method.

This instrument is used to measure the moisture permeability of various kinds of fabrics,space cotton and other nonwoven garments.

Moisture permeability can reflect the performance of clothing perspiration and steam, and it is one of the important indicators of clothing comfort and hygiene
