Thermal resistance and Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity are critical parameters in determining whether a material is an insulator or a good heat conductor. These properties are essential when designing thermal management systems to prevent overheating and improve energy efficiency.

The TCT 716 Lambda is our first Guarded Heat Flow Meter (GHFM) with a temperature range spanning from -10 to 300°C enabling the study of a wide range of solid, rigid or incompressible materials.

About the GHFM Method

The Guarded Heat Flow Meter (GHFM) method involves placing a specimen between two plates controlled at different temperatures. Multiple RTD sensors measure the temperatures on each side, while heat flux sensors measure the heat flow caused by the temperature gradient.

To prevent lateral heat loss an insulating layer (active guard) is incorporated. This design allows for high accuracy and repeatability in measuring thermal conductivities in the medium range (0.1 to 30 W/(m·K)).
