Thermometers: Understand the options

Contactless thermometers

Contactless thermometers measure temperature without touching the body.

Temperature is found by scanning infrared heat from the forehead or skin, typically at a distance of 1/2 to 2 inches (1.3 to 5 centimeters). Check the manufacturer's instructions, as the distance may be different for each brand. Contactless thermometers used on the forehead are called temporal artery thermometers.
