EXERGEN^® Temporal Artery Thermometer TAT-5000 was invented by Dr. Francesco Pompei, a Harvard research scientist who held over 100 patents including NASA precision temperature sensor. In order to obtain non-invasive and accurate core body temperature for clinical use, Dr. Pompei, in the light of the distribution and course of superficial temporal artery, developed a high-precision medical temporal artery thermometer which features High-frequency Continuous Thermal Scanning, Arterial Heat Balance and other advanced technologies and integrates safety, accuracy, rapidness, gentleness and usability, thus changing the way the world takes temperature. Currently, TAT has been nominated by world leading brands as GE, Philips, Mindray, Nihon Kohden, etc., to be configured in their high-end vital sign detectors for clinical body temperature measurement.
