In a measuring arrangement for the contactless determination of the temperature of solid bodies, an air stream flows through a heating chamber, a following prechamber, a following housing and an intermediate space containing a differential thermocouple and existing between the housing and the surface of the body, into which intermediate space the air stream can be blown, forming an air cushion, and can be blown out again at its circumference, one thermocouple measuring point being arranged in the area of the air stream blown in and the other thermocouple measuring point being arranged in the area of the air stream blown out and both being connected to the heating chamber via a controller. To increase the measuring accuracy, several through holes are provided in the edge area of the housing via which the air stream can be blown into the intermediate space and can be partially blown out again via a central blind hole containing the other thermocouple measuring point.
