LFY-232B Warm Body Dummy Thermal Performance Tester

Main purpose

The warm body dummy testing method is used to test the thermal insulation performance of products such as textiles, clothing, sleeping bags, and thermal protection suits. During the process of simulating the heat exchange between the human body, textiles, and the environment, by analyzing the relationship between the temperature difference between the skin surface of the warm body dummy and the environmental temperature, as well as the non-evaporation heat dissipation rate per unit area of the body surface, the thermal resistance of the clothing is calculated. This method truly simulates and comprehensively tests the cold and hot comfort performance of textile and clothing products.
