A clinical thermometer is a special type of liquid-in-glass thermometer although electronic versions are also available. It has a smaller and more accurate temperature range of measurement (35°C to 42°C).

Specific features of the liquid-in-glass clinical thermometer are:

A 'kink' in the glass tube which breaks the mercury as it contracts, storing the highest temperature reading.The glass tube is shaped like a lens to magnify the thin mercury thread. Shaking the thermometer resets the mercury back into the bulb.

The normal body temperature for a human being is 37°C. If this temperature rises above 38°C then the person has a fever. If it lowers past 34°C then the person has hypothermia. Extreme temperature rises and falls will cause serious damage (e.g. frostbite) to the body or even death.
