2. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   Mercury thermometer (mercury-in-glass thermometer) for measurement of room temperature. [1]A thermometer is a device that measures temperature (the hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space).

3. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.

4. Pyrometer - Wikipedia

   en.wikipedia.org/wiki/Pyrometer

   The word pyrometer was originally coined to denote a device capable of measuring the temperature of an object by its incandescence, visible light emitted by a body which is at least red-hot. [1] Infrared thermometers , can also measure the temperature of cooler objects, down to room temperature, by detecting their infrared radiation flux.

5. List of measuring instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_measuring_instruments

   An active calorimeter lacking a temperature measurement device. This includes thermal mass or temperature coefficient of energy, reaction energy, heat flow, ... Calorimeters are called passive if gauged to measure emerging energy carried by entropy, for example from chemical reactions.

6. List of weather instruments - Wikipedia

   Thermometer for measuring air and sea surface temperature; Barometer for measuring atmospheric pressure; Hygrometer for measuring humidity; Anemometer for measuring wind speed; Pyranometer for measuring solar radiation; Rain gauge for measuring liquid precipitation over a set period of time; Wind sock for measuring general wind speed and wind ...

7. Thermodynamic instruments - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_instruments

   A calorimeter is a device which is used to measure and define the internal energy of a system. Some common thermodynamic meters are: Thermometer – a device which measures temperature as described above; Barometer – a device which measures pressure, most notably atmospheric pressure. [3] An ideal gas barometer may be constructed by ...
