What is the instrument used to measure the air temperature?
Measuring Humidity; A Psychrometer is an instrument used to measure relative humidity. It traditionally consists of two thermometers, one covered with a wet cloth. Evaporation cools this thermometer below the actual air temperature, recorded on the dry thermometer.
The instrument used to measure temperature is usually the thermometer, although a thermistor can also be used. Learn about the way in which a thermometer works on the basis of liquid expansion with help from a science teacher in this free video on physical science.
- One of the most common devices for measuring temperature is the glass thermometer. This consists of a glass tube filled with mercury or some other liquid, which acts as the working fluid.
- Units of Temperature: from fahrenheit to celsius to kelvin and back. Degrees Fahrenheit, (developed in the early 1700's by G. Daniel Fahrenheit), are used to record surface temperature measurements by meteorologists in the United States.
An outdoor thermometer used to measure the average thermal energy in the air. A thermal infrared camera used to image heat. . Heat is measured in quantities called joules (pronounced the same as jewels) in the metric system and in British Thermal Units (BTU) in the English system. Heat can also be measured in calories.
- A force meter is used to measure forces. Forces can be measured using a force meter. Force meters contain a spring connected to a metal hook. The spring stretches when a force is applied to the hook.

- In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stop watches are also used to measure time in some sports.
Pyrometer. Pyrometer, device for measuring relatively high temperatures, such as are encountered in furnaces. Most pyrometers work by measuring radiation from the body whose temperature is to be measured. Radiation devices have the advantage of not having to touch the material being measured.
- Yep, the answer is a bolt of lightning, which can reach temperatures of roughly 30,000 kelvins (53,540 degrees Fahrenheit). The sun, on the other hand, is eclipsed in this case - its surface temperature is just 6,000 kelvins (10,340 degrees Fahrenheit).
- By measuring the brightness distribution of the sun and fitting it with Planck''s law, the Sun''s temperature can be estimated. The sun emits maximum at the visible or yellow wavelength and the corresponding temperature is about 6000 degree Kelvin.
- Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. At night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get cold at night, dropping to below 40F, which is definitely coat weather.
