FIELD: measurement technology. SUBSTANCE: device includes temperature converter and infrared imaging camera. Temperature converter comes in the form of grid of filaments. Filament material has thermal conductivity amounting to 0.95-1.05 thermal conductivity of gas, filament thickness is 10-5- mcm and distance between them amounts to 100-200 filament thicknesses. Besides that grid carries thermal indication coat. Such design of device for measuring temperature field of gas flow provides for momentary measurement of temperature field of gas flow in maximally permissible area of gas flow. EFFECT: decreased measurement time, enhanced measurement accuracy, reduced number of operations and their simplification, increased convenience and safety of personnel conducting such operations. 2 dwg
