FIELD: measuring equipment.
SUBSTANCE: invention can be used for measuring emissivity of coatings. Device, containing identical thermal radiator and heat sink, equipped with Peltier thermoelectric batteries connected to the output of the temperature regulators on the surface of which there are heat flux sensors arranged in series and connected to signal meter and coated at outer side with the investigated material heat-conducting plates connected to inputs of the thermal sensors of temperature regulators. Cavity of the heat exchanger represents a fixed gap between parallel plates of heat radiator and heat release.
EFFECT: high accuracy and wider temperature range of measuring of emissivity.
