Abstract:
An infrared thermometer, in particular a clinical thermometer, comprising a probe (1) in which an infrared sensor (106) and an optical waveguide (104) are arranged and on which a probe cover or protective film (101) is mountable, with a detector (108) detecting the conditions of the probe cover or protective film (101) as ""installed"" or ""not installed"", and with an evaluation unit (402) for the signals supplied by the infrared sensor (106) and the detector (108), said optical waveguide (104) being sealed tight in an end area by means of a window (103) transparent to infrared radiation, and during a temperature measurement the evaluation unit (402) performs the evaluation of the signal supplied by the infrared sensor (106) according to either a first or a second approach (202, 203) depending upon whether the signal supplied by the detector (108) indicates that the probe cover or protective film is ""installed"" or is ""not installed"".
