The DHT® Thermal & Moisture Resistance Tester is a high-precision instrument designed to measure the thermal resistance (Rct) and water vapor resistance (Ret) of various materials under steady-state conditions. It is suitable for testing textiles, films, coatings, foams, leather, and multi-layer composites. This device provides critical data for evaluating product comfort and functionality, and is widely used in the textile, footwear, and construction material industries for research and quality control.
