Thermal Conductivity and Diffusivity

Thermal conductivity, thermal diffusivity and specific heat capacity define a material’s ability to store and transfer heat. The precise and accurate measurement of these properties is critical for any process or material, which experiences a large or fast temperature gradient, or for which the tolerance for temperature change is exacting. Accurate values of these properties are essential for modeling and managing heat, whether the component of interest is called on to insulate, conduct, or simply withstand temperature changes. Information about these properties are routinely used in heat transfer models of all complexities. Thermophysical property measurements also reflect important information about material composition, purity and structure, as well as secondary performance characteristics such as tolerance to thermal shock.

TA Instruments provides a range of instruments for the precise and accurate measurement of heat transfer properties of a wide range of material types and temperatures. The DTC-25 and DTC-300 Heat Flow Meters provide direct measurement of thermal conductivity of low to medium conductivity materials according to ASTM E1530. The Discovery Flash Diffusivity instruments measure thermal diffusivity and specific heat capacity according to the Light Flash Method, which is ideal for moderate to high conductivity materials over the widest range of temperatures. Unique source and detector technology makes the Discovery Flash Diffusivity the most accurate platform for measurements by the Flash Method.
