2. International Temperature Scale of 1990 - Wikipedia

   en.wikipedia.org/wiki/International_Temperature...

   The International Temperature Scale of 1990 (ITS-90) is an equipment calibration standard specified by the International Committee of Weights and Measures (CIPM) for making measurements on the Kelvin and Celsius temperature scales. It is an approximation of thermodynamic temperature that facilitates the comparability and compatibility of ...

3. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   Other thermometers to be calibrated are put into the same bath or block and allowed to come to equilibrium, then the scale marked, or any deviation from the instrument scale recorded. [39] For many modern devices calibration will be stating some value to be used in processing an electronic signal to convert it to a temperature.

4. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   The theoretical basis for thermometers is the zeroth law of thermodynamics which postulates that if you have three bodies, A, B and C, if A and B are at the same temperature, and B and C are at the same temperature then A and C are at the same temperature. B, of course, is the thermometer.

5. Scale of temperature - Wikipedia

   en.wikipedia.org/wiki/Scale_of_temperature

   Scale of temperature is a methodology of calibrating the physical quantity temperature in metrology.Empirical scales measure temperature in relation to convenient and stable parameters or reference points, such as the freezing and boiling point of water.

6. Calibration - Wikipedia

   en.wikipedia.org/wiki/Calibration

   The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...

7. Resistance thermometer - Wikipedia

   en.wikipedia.org/wiki/Resistance_thermometer

   Resistance thermometers, also called resistance temperature detectors ... A common fixed-point calibration method for industrial-grade probes is the ice bath. The ...

8. Mercury-in-glass thermometer - Wikipedia

   en.wikipedia.org/wiki/Mercury-in-glass_thermometer

   By performing the same experiment over and over again, he discovered that ice always melted at the same calibration mark on the thermometer. He found a similar fixed point in the calibration of boiling water to water vapour (when this is done to high precision, a variation will be seen with atmospheric pressure; Celsius noted this). At the ...

9. Recording thermometer - Wikipedia

   en.wikipedia.org/wiki/Recording_thermometer

   A type of chart recorder, one end of a bi-metallic strip is attached to a long, light metal lever that holds a special pen. Tiny movements of the bimetallic strip cause much larger movements of the free end of the lever and the pen.
