Thermal conductivity is a physics quantity representing the heat conducting characteristic of a matter,
but change of material structure and different content of impurity have obvious influence on it, therefore, the thermal conductivity of material often needs to be measured on particular requires. Two of steady state method and dynamic method are available for measuring thermal conductivity. By steady state method, the specimen should be preheated in result to make heat conduct from high temperature to the low inside the specimen due to reason of temperature difference, thus the temperature of each point insider the specimen vary with the speeds of heating and conducting, and then give proper control to experiment conditions and parameters to make the process of heating and conducting reach to a balanced state, with which the specimen will have a stable temperature distributed inside. Based on it, the thermal conductivity can be found out. This apparatus is designed adopting the steady state method for measuring the poor conductor (such as rubber), with which we can learn the experimental technique of utilizing the rate of heat release of object to find out conducting speed. The apparatus, with steady state method, is used for measuring the poor conductor. It is the second generation, the heating disc of which is changed to of self-adapting temperature control by monolithic processor with 0.1°C of reading resolution. The heat emission disc is designed with integrated sensor for temperature measurement, the reading resolution of which is 0.1°C. With firm structure, easy measurement and control, the apparatus has been widely applied on heat experiment of general physics in universities and colleges.
