The modified theory of the bi-calorimeter with the dimidiated metallic core is described. Between two blocks of the core a sample of material (solid or gas) is placed and the heating of only one block begins. The temperature of the blocks in function of time is recorded. From the obtained data it is possible to calculate the temperature difference between the blocks and the heat flux running through the sample. Using the Fourier's law the thermal conductivity of the sample material is calculated. The partition of electrical power between the heated and the passive block was independent of temperature. By the application of a thin air layer which separates the block and the sample material, the undefined contact resistance is eliminated.
