<p>A radiation thermometer wherein a temperature-measuring switch is depressed to start the operation for measuring a body temperature, a probe is inserted in a hole of a living body, infrared rays are received from the interior of the hole to calculate a temperature, and the maximum value of the measured temperature data is displayed as a body temperature. The thermometer comprises an operation-judging means provided for judging whether or not the temperature-measuring switch is properly operated so as to prevent the temperature from being measured or displayed by such an operation that the temperature measurement start switch is depressed after the probe has been inserted in the external auditory meatus or that the switch is inadvertently depressed again after the probe has been inserted in the external auditory meatus despite the switch has been properly depressed before it is inserted in the external auditory meatus. When the switch is erroneously depressed, an erroneous operation alarm is produced, or a normal operation for measuring the temperature will not be affected by erroneous operation.</p> |
