Complex contactless flash thermal analyser of low conductive materials

In the paper we present theoretical and experimental results of two variants of contactless thermal analyzer (CTA) for determination of specific heat capacity, thermal diffusivity and thermal conductivity for different sample sizes. Measuring system under investigation is fully automatic (including of sample illumination), contactless and relative precise (sensitivity ∼ units of percent). Results obtained by this method were tested by an independent contact method. All of the obtained results by presented apparatus, were obtained on rubber blends and they are in a very good coincidence with contact method.
