ABSTRACT:
An apparatus for measuring thermal conductivity of a desired sample liquid, even of a transparent sample liquid, on the basis of thermal diffusion to the sample liquid from a small and thin metal disc which is heated by laser flash. The sample liquid is inserted within a small gap which is formed between the metal disc and a sample holding block, and the thermal diffusion can be measured by a thermocouple connected to the metal disc.
