In a method for measuring the surface temperature of a blackbody radiator, this surface of the blackbody radiator is constructed as a thermocouple. For this purpose, the radiator (a cavity or an extended surface) can be produced, for example, from copper whose radiating surface (or parts thereof) is coated by electroplating (or in some other way) with copper/nickel (constantan), for example. The radiating surface then represents a copper/constantan thermocouple which in conjunction with a second copper/constantan element, which is at a reference temperature of, for example, 273 K, permits highly precise measurements of the radiator temperature, and thus also a more precise temperature control.
