Ear
Other kinds of medical thermometers exist, such as the tympanic thermometer that measures the temperature of the tympanum by infrared measurement, The thermometer has a projection (protected by a one-time hygienic sheath) which contains the infrared probe; the projection is gently placed in the ear canal and a button pressed; the temperature is read and displayed within about a second. These thermometers are used both in the home? and in medical facilities.


Temporal artery
A newer development is the Temporal artery thermometer, which uses the infrared principle to accurately report a patient's temperature, with comparable accuracy to rectal thermometry.[citation needed]


Forehead
The band thermometer is applied to the patient's brow. It is typically a band coated with different temperature-sensitive markings using liquid-crystal or similar technology; at a given temperature the markings (numerals indicating the temperature) in one region are at the right temperature to become visible. This type gives an indication of fever, but is not considered accurate.
