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.
1. Place the thermometer 5 feet above the ground (+/- 1 ft.). A thermometer too low will pick up excess heat from the ground and a thermometer too high will likely have too cool of a temperature due to natural cooling aloft. 5 ft. is just right. 2.The thermometer must be placed in the shade.If you put your thermometer in full sunlight, direct radiation from the sun is going to result in a temperature higher than what it should be. 3. Have good air flow for your thermometer.This keeps air circulating around the thermometer, maintaining a balance with the surrounding environment. Therefore, it is important to make sure there are no obstructions blocking your thermometer such as trees or buildings.. Have good air flow for your thermometer.
