The thermal imaging inspection is one of the main technical diagnostics development directions , allowing to control the thermal condition of equipment and structures without removing from the exploitation at an early stage of defects’ development, while reducing the technical inspection and defect detection costs. During thermal inspection essential is to pay a special attention to the analysis of the measurement errors occurred causes. One of the main issues we face with while calculating the temperature in compliance to the results of thermal imaging measurements, relates to the uncertainty in the assessment of the object’s surface emissivity. The effected study has been aimed onto researching the materials’ emissivity influence onto the thermal control method accuracy. The studies’ results demonstrate a significant impact of materials’ emissivity onto accuracy of temperature non-contact measuring method. Elaborated is the methodology of calculating the measurement uncertainty, due to the error in setting the coefficient emissivity. Results obtained can be used in various industries for more accurate actual temperature estimation for a real object.
