Thermal Conductivity Tester (Heat Flow Method) is a precision instrument designed for measuring thermal conductivity, thermal resistance, and interfacial contact thermal resistance of thin thermally conductive and electrically insulating solid materials. The system is fully designed and manufactured in accordance with ASTM D5470-2017. adopting the steady heat flow method with optimized temperature gradient measurement. With automated pressure loading, automatic thickness measurement, multi-point temperature detection, and computer-controlled operation, the instrument enables accurate evaluation of thermal resistance curves under different pressures and temperatures. It is widely used for thermal performance analysis of solid sheet materials, interface materials, and high-conductivity components in laboratory and industrial environments.
