LFY-216A fabric moisture permeability tester
The main purpose
LFY-216A fabric moisture permeability tester uses the moisture permeable cup moisture absorption method to determine 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 has a PID self-tuning temperature/humidity controller (with a high-precision PT100 sensor), and the temperature and humidity can be set on the instrument panel as required.
2. Digital display timer.
3. Double-layer hollow glass door and pure stainless steel liner experiment box.
