Thermal Diffusivity measurement system by Xe flash method TD-1

Capable of evaluation of heat radiation film in the thickness direction and anisotropy
The most suitable system for the evaluations of heat dissipation films etc. By using Xenon lamp, it enables to minimize the damage to the sample. Sample anisotropy can also easily measure by using the original attachment as an option.
