As a result of the analysis of methods for measurement thermophysical characteristics for the application in information-measuring system chosen the method with use of symmetrical scheme of placement of two identical heat flux sensors. To ensure a uniform thermal field of the sample surfaces, it is proposed to additionally introduce security heaters around the perimeter of the measuring cell. Calorimetric methods for measuring the thermophysical and thermoradiation characteristics materials, in particular, energy-efficient glass, thin coatings, concrete mixtures in a wide temperature range have been developed and implemented. An indirect method of metrological characteristics research for information-measuring system based on measurement of values metrologically provided in Ukraine without the use of working standards of thermal conductivity was approved, which reduced the uncertainty of measuring thermophysical characteristics.
