This solution concerns the method of realisation of a procedure of a contact-free temperature measuring regardless of substance emissivity, i.e. based on radiation pyrometry, while the solution can be used in all fields of the national economy. The purpose thereof is also to permit an application of this method in a high-temperature and low-temperature extent area, where only minimum preconditions and data are necessary. The task rests in determination of the actual temperature of an object being possible even in case of inaccurate knowledge of the emissivity, particularly in cases where the emissivity is non-permanent. The essence thereof lies in the fact that by means of a pyrometric device sensitive to certain spectral areas, input values are received step by step as band signals of measured object radiation without ancillary radiation of the known spectral composition, and thereafter, with such ancillary radiation. These values are then recorded in the PC. The PC connects the input values so that the unknown values, such as the actual temperature of the object, and spectral emissivity are determined by an iterative solution of the non-linear equation system.
