WebbA hand-held, battery-powered, electronic instrument designed to measure a patient's body temperature. It comprises of an electronic unit that detects and converts the changes in temperature into variations of some electrical characteristic, e.g., resistance or voltage. A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). 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 co…
