| thermometer | <physics> An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompained by proportional changes in their volumes or dimensions. The thermometer usually consists of a glass tube of capillary bore, terminating in a bulb, and containing mercury or alcohol, which expanding or contracting according to the temperature to which it is exposed, indicates the degree of heat or cold by the amount of space occupied, as shown by the position of the top of the liquid column on a graduated scale. See Centigrade, Fahrenheit, and Reaumur. To reduce degrees Fahrenheit to degrees Centigrade, substract 32 deg and multiply by 5/9; to reduce degrees Centigrade to degrees Fahrenheit, multiply by 9/5 and add 32 deg . Air thermometer, Balance thermometer, etc. See Air, Balance, etc. Metallic thermometer, a form of thermometer indicating changes of temperature by the expansion or contraction of rods or strips of metal. Register thermometer, or Self-registering thermometer, a thermometer that registers the maximum and minimum of temperature occurring in the interval of time between two consecutive settings of the instrument. A common form contains a bit of steel wire to be pushed before the column and left at the point of maximum temperature, or a slide of enamel, which is drawn back by the liquid, and left within it at the point of minimum temperature.

| thermography |
In medicine, a procedure in which a heat-sensing infrared camera is used to record the surface heat produced by different parts of the body. Abnormal tissue growth can cause temperature changes, which may show up on the thermogram. Thermography may be used to diagnose breast cancer and other tumors.
