Abstract

The invention is directed to an infrared radiation thermometer, in particular an ear thermometer, having a probe head (10) whose outer diameter and/or shape is variable by an elastic arrangement (4, 14, 24). This enables the probe head to conform itself automatically to the size and/or contour of the body cavity or to be conformed manually. The thermometer is therefore equally well suited for both children and adults, although their ear canals differ in diameter.
