Thermometer : Digital thermometers are temperature-sensing instruments that are easily portable, have permanent probes, and a convenient digital display. The way a digital thermometerworks depends upon its type of sensor. Sensor types include resistance temperature detector (RTD), thermocouple and thermistor.

A thermometer has two important elements: a temperature sensor (e.g. the bulb of a mercury in glass thermometer) or the pyrometric sensor in aninfrared thermometer in which some change occurs with a change in temperature; and some means of converting this change into a numerical value (e.g. the visible scale that is marked on a mercury-in-glass thermometer or the digital readout on an infrared model). Thermometers are widely used in technology and industry to monitor processes, in meterology, in medicine, and in scientific research.
