They include the thermal expansion of solids or liquids with temperature, or the change in pressure of a gas on heating or cooling. Radiation-type thermometers measure the infrared energy emitted by an object, allowing measurement of temperature without contact.Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and scientific research.he precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 Â°C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 Â°C.
Surface air temperature. See also: Instrumental temperature record. The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a Stevenson screen, a standardized well-ventilated white-painted instrument shelter. The thermometers should be positioned 1.25â2 m above the ground.
