Textile Water Vapor Resistant Tester
Product Description
Product introduction:
The tester for testing the water vapor transmission properties of textiles and textile composites (especially sportswear fabrics). The instrument is equipped with 8 test containers and standard breathable fabric cover, sample clamping ring and precision drive system.
Working principle:
In the environment of constant temperature and humidity, cover the sample on the sample dish with water, after a certain period of time, the water vapor permeates from the fixed sample area. Pass rate and water vapor transmission index.
Accessories:
PVC electrical insulating tape: width 10~15mm
Standard fabric:
High-strength polyester yarn weaving, pore size 18μm, yarn diameter 32μm, thread count: 196.1 threads/cm, elongation 12.5%
Burette:
Capacity greater than 50ml
Auxiliary tools:
Electronic balance (sold separately): The balance for weighing the filling must be accurate to 0.001g
Standards Compliant: BS 7209, BS 3424
