Abstract: This study is devoted to the experimental studies of Thermo Physical Properties (TPP) of objects. The existing methods of TPP determination are analyzed. They presented the algorithm developed by the researcher for TPP determination of the object under study. They described the operation of the unit for TPP (heat transfer coefficient, heat transfer resistance and specific thermal characteristic) determination of the object under study. The formulas are given required for TPP calculation. The experimental results of the study are presented. The main advantages of the developed unit are described.
