Технические характеристики
| Temperature Range | RT to 1250°C |
|---|---|
| Heating rate (max.) | 50 K/min |
| Measured thermal properties | Thermal Diffusivity Thermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature. Thermal diffusivity and specific heat capacitiy (and calculation of Thermal Conductivity Thermal 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 ) |
