Temporal Thermometer

a handheld thermometer that measures the temperature of a branch of the superficial temporal artery by pointing an infrared scanner directly at the forehead or lightly passing the scanner across the skin of the forehead : FOREHEAD THERMOMETER

In one study published last year in the American Journal of Critical Care, both oral and temporal artery thermometers were more accurate and precise than temperatures taken in the ear or under the armpit.
