Background. Information-measuring system carries out non-destructive control and measurement of the parameters of thermal properties of solid materials and products – construction, plastic, thermal insulation and other that affect the quality of products in production. Violation of the performance of individual structural components of the measuring channel system leads to changing the reliability of the resulting measurement information and increasing uncertainty determined on the basis of its thermo-physical properties of materials parameters. This situation relates to the refusal of information-measuring system.
Matherials and methods. Research performance information measurement system and its structural components is carried out using the classical theory of evaluating the reliability of information and measurement systems and correction algorithm developed technical imperfections of informationmeasuring system.
Results. Introduced system of parallel redundancy of the main structural components of measurement system channel and correction algorithm for their technical imperfections, which allowed to increase the reliabilities of information-measuring system of thermal properties of materials parameters. 
Conclusions. Improving the reliability of informationmeasuring system ensures the reliability of the measurement information, the accuracy of the determined parameters of thermal properties of materials that contribute to the quality in their production
