Abstract
An ear-type thermometer which measures body temperature using a temperature detection elementthat detects ambient temperature and an infrared detection elementthat detects infrared radiation from a measurement site within the aural cavity, the 2 elements housed in a probe, wherein the ear-type thermometer comprises a probe coverwhich can be detachably provided with the probe, a detection switchwhich detects that the probe cover is attached or detached to the probe, and two temperature conversion coefficientsandwhich corrects body temperature based on the detection result from the two detection elements. Further, the thermometer comprises a detection switchwhich detects that the probe cover is attached or detached to and from the probe, a temperature conversion coefficientwhich corrects body temperature based on detection results from the two detection elements, a control unitwhich determines whether the probe cover has exceeded the usage count limit or not using an actual usage count, a speakeror a liquid crystal display unit which alerts need to replace the probe cover when the usage count limit has been exceeded.
