This article provides an experimental assessment of three commercially available clinical thermometers, using different thermal infrared sensors. This kind of thermometer measures body temperature by detecting infrared radiation from the tympanic membrane. These thermometers are growing in popularity thanks to their simplicity of use, rapid response and minimal distress to the patient. The purpose of the laboratory tests presented here was to assess the effect of varying ambient temperature and varying simulated patient temperature on the performance of the three infrared tympanic thermometers.
