A patented approach to infrated thermometry based on the use of a standard pyrosensor has resulted in the development of two new infrared tympanic thermommeters, one for professional use, the other for home use. Both were tested to evaluate accuracy in the laboratory and to evaluate equivalence to standards correlation to standards, and precision in human subjects. Acuracy was found to be wel within ASTM standards on both models. Mean ear temperatures were 0.2 0C below oral and 0.70C below bladder temperature. Correlations between ear and oral and ear and bladder te mperatures were r=77 to .84. Repeatability in the same ear was very high at r=.95 (left> and .97 (right). REproducibility between left and right ear ranged from r=.89 to .92.
