Temperature Thermometers
The mercury medical thermometer of the past work the same way as a meteorological maximum
thermometers.
The thermometer consists of a mercury ball attached to a tube.
There is a constriction in the neck close to the bulb. As the temperature increases, the expanding force of the mercury pushes up the tube through the constriction. When the temperature falls, the
column of mercury breaks at the constriction and cannot return to the bulb, it remains stationary in the tube. To reset the thermometer, flicked a few times.
When it is designed for use in humans, the typical range of this kind of thermometer is from about 35C to 42C or 89.6F to 109.4F.
The markings on the side of thermometers will give you the temperature.
Close-up of a maximum thermometer. The break in the column of mercury is visible.In the 1990s, mercury-based
thermometers were found too risky to handle; the vigorous swinging needed to reset
a mercury maximum thermometer makes it easy to accidentally break it, and spill the poisonous mercury.
Mercury thermometers have largely been replaced with
digital thermometers, or, more rarely, thermometers based on liquids other than mercury (such as heat-sensitive
liquid crystals). Other modern options include digital Infrared contact or non-contact thermometers, which are also called
forehead thermometers. Most medical thermometers may be used
to take oral, axillary, vaginal, or rectal temperatures.
