LFY-216B fabric moisture permeability tester

Name:LFY-216B fabric moisture permeability tester

Details

The main purpose
LFY-216B Fabric Moisture Permeability Tester uses a moisture-permeable cup moisture absorption method to measure the ability of water vapor to permeate fabrics. This instrument is used to measure the moisture permeability (vapor) of various fabrics (including moisture-permeable coated fabrics), cotton wool, space cotton and other non-woven fabrics used in clothing. Moisture permeability can reflect the performance of clothing perspiration and steam, and is one of the important indicators for identifying the comfort and hygiene of clothing.
Instrument characteristics
1. The instrument main cabinet and instrument control cabinet with refrigeration system.
2. The wind speed is adjustable.
3. For the American standard, there are 4 square moisture-permeable cups for measuring thick samples and 4 round moisture-permeable cups for thin samples; 3 moisture-permeable cups for national standards.
4. With PID self-tuning temperature/humidity controller.
5. Digital display timer.
6. Start timing button/stop timing button.
