Device and procedure for radiometric calibration of thermal infrared cameras. The device comprises an isolated receptacle (2) intended to contain a camera (1) to be calibrated, a black body simulator (3) with an access hole (4), and a heating module (5) and temperature control, connected to the receptacle (2) and to the black body simulator (3). Making use of the device, the procedure comprises the steps of: progressive increase in the temperatures of the black body simulator (3) and of the receptacle (2) in pre-established intervals, and for each temperature, capturing at least three images with values of temperature and at least three with digital values, which allows the calibration of the camera (1) at different working temperatures, as well as the measurement of a large number of temperature values, increasing the accuracy of camera calibration (1) .
