Medical or clinical thermometers are used for measuring human or animal body temperature. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature)

Nowadays the most used thermometers are electronic thermometers because of their convenience and the fact that display readings to great precision (0.1 °C or 0.2 °F, sometimes half that). But a recent research shows that the current generation of electronic, digital clinical thermometers, in general, may not be sufficiently accurate or reliable to replace the traditional glass/mercury thermometers.
