This Online course explains the
- the hardware of the instrument
- the theory of the HFM method
- which factors have an influence on the measurements
- how to prepare different types of samples
- how to calibrate the equipment
- how to start a 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 measurement
