Water Vapour Permeability Tester, to determine the resistance of textiles and textile composites (particularly action wear fabrics) to water vapour penetration. Water vapour permeability tester consists of 8 containers with water reservoirs, a standard permeable fabric cover, sample holder ring and precision drive system.

Water vapour permeability tester should work in conditioning room or conditioning chamber. Wet-cup can be converted to do different test.
