The Exergen Temporal Artery Thermometer (Model TAT-2000C) is a non-invasive, infrared forehead thermometer designed for fast, easy, and accurate temperature measurement at home. Ranked the #1 thermometer brand in proven accuracy by more than 50 published clinical studies, it is the preferred choice of nurses and pediatricians worldwide.

The TAT-2000C uses Exergen's patented TemporalScanner technology, which captures naturally emitted infrared heat from the skin over the temporal artery—taking approximately 1,000 readings per second and locking in the most accurate result. The patented Arterial Heat Balance (AHB) system automatically measures and compensates for ambient temperature, delivering a precise arterial temperature that reflects the body's true core temperature as accurately as invasive methods.

To use, press and hold the button, lightly scan the thermometer across the forehead, and release to read the temperature. The soft-glow display makes results easy to see in a darkened room, making this thermometer ideal for checking the temperature of a sleeping infant or adult without disturbing them. The device retains the last 8 temperature readings for convenient reference.

Because it scans the forehead rather than inserting into the ear, mouth, or rectum, the TemporalScanner is more comfortable and hygienic than traditional thermometers. It eliminates the positioning challenges that make ear thermometers prone to inaccurate readings, and it is unaffected by factors such as drinking, coughing, or mouth breathing that can skew oral temperatures.
