• Innovative method of temperature assessment using infrared technology • Noninvasive • EXGTAT5000 is the standard Exergen TAT-5000 model that measures the core body temperature • EXG124375 is the same thermometer as EXGTAT5000 but has an internal offset that makes temperature readings more similar to those of an oral thermometer (about 1 degree lower than EXGTAT5000 readings) • EXGTAT5000 and EXGTAT2000 are both compatible with probe covers (EXG134203, EXG134203H)
