  2. 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.

  3. 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.

  4. 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).

  5. 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 ...

  6. Resistance thermometer - Wikipedia

    en.wikipedia.org/wiki/Resistance_thermometer

    If process temperatures are between −200 and 500 °C (−328.0 and 932.0 °F), an industrial RTD is the preferred option. Thermocouples have a range of −180 to 2,320 °C (−292.0 to 4,208.0 °F), [9] so for temperatures above 500 °C (932 °F) it is the contact temperature measurement device commonly found in physics laboratories.

  7. Distributed temperature sensing - Wikipedia

    en.wikipedia.org/wiki/Distributed_temperature...

    Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances.
