- A new version of the hot-wire method for measuring thermal conductivity is proposed. The sheath of a differential Thermocoax wire is heated by an electric current and the temperature is recorded before, during and after heating. An on-line desk computer fits the theoretical expression for the temperature to the data. Thermal conductivity as well as heat capacity for a fluid or plastic medium surrounding the wire may be determined.
