A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. 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 ...
A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury ...
As a temperature indicator it used red wine. (Rømer scale), The temperature scale used for his thermometer had 0 representing the temperature of a salt and ice mixture (at about 259 s). 1709 — Daniel Gabriel Fahrenheit constructed alcohol thermometers which were reproducible (i.e. two would give the same temperature)
Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer. Other important devices for measuring temperature include:
Temperature can be measured from the mouth, rectum, axilla (armpit), ear, or skin. Oral, rectal, and axillary temperature can be measured with either a glass or electronic thermometer. [ 11 ] Note that rectal temperature measures approximately 0.5 °C higher than oral temperature, and axillary temperature approximately 0.5 °C less than oral ...
A medical thermometer showing a temperature reading of 38.7 °C (101.7 °F) Taking a human's temperature is an initial part of a full clinical examination. There are various types of medical thermometers, as well as sites used for measurement, including: In the rectum (rectal temperature) In the mouth (oral temperature)
A low temperature thermometer can be placed in the rectum, esophagus or bladder. Esophageal measurements are the most accurate and are recommended once a person is intubated. [2] Other methods of measurement such as in the mouth, under the arm, or using an infrared ear thermometer are often not accurate. [2]
The resolution of liquid crystal sensors is in the 0.1 °C (0.2 °F) range. Disposable liquid crystal thermometers have been developed for home and medical use. For example if the thermometer is put onto someone's forehead, it will change colour depending on the temperature of the person's body. There are two stages in the liquid crystals:
