2. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   One must be careful when measuring temperature to ensure that the measuring instrument (thermometer, thermocouple, etc.) is really the same temperature as the material that is being measured. Under some conditions heat from the measuring instrument can cause a temperature gradient, so the measured temperature is different from the actual ...

3. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   Thermometers utilize a range of physical effects to measure temperature. Temperature sensors are used in a wide variety of scientific and engineering applications, especially measurement systems. Temperature systems are primarily either electrical or mechanical, occasionally inseparable from the system which they control (as in the case of a ...

4. Thermodynamic instruments - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_instruments

   Although pressure is defined mechanically, a pressure-measuring device called a barometer may also be constructed from a sample of an ideal gas held at a constant temperature. A calorimeter is a device which is used to measure and define the internal energy of a system. Some common thermodynamic meters are:

5. List of weather instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_weather_instruments

   Weather stations typically have these following instruments: 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 ...

6. Thermocouple - Wikipedia

   en.wikipedia.org/wiki/Thermocouple

   This secondary measurement is used to compensate for temperature variation at the junction block. The thermocouple junction is often exposed to extreme environments, while the reference junction is often mounted near the instrument's location. Semiconductor thermometer devices are often used in modern thermocouple instruments.

7. List of measuring instruments - Wikipedia

   en.wikipedia.org/wiki/List_of_measuring_instruments

   A measuring cup, a common instrument used to measure volume. Buoyant weight (solids) Eudiometer, pneumatic trough (gases) Flow measurement devices (liquids) Graduated cylinder (liquids) Measuring cup (grained solids, liquids) Overflow trough (solids) Pipette (liquids) If the mass density of a solid is known, weighing allows to calculate the volume.

8. Pyrometer - Wikipedia

   en.wikipedia.org/wiki/Pyrometer

   The tuyère pyrometer is an optical instrument for temperature measurement through the tuyeres, which are normally used for feeding air or reactants into the bath of the furnace. A steam boiler may be fitted with a pyrometer to measure the steam temperature in the superheater.

9. Stevenson screen - Wikipedia

   en.wikipedia.org/wiki/Stevenson_screen

   Stevenson screens may also be known as a cotton region shelter, an instrument shelter, a thermometer shelter, a thermoscreen, or a thermometer screen. Its purpose is to provide a standardised environment in which to measure temperature, humidity, dewpoint, and atmospheric pressure. It is white in color to reflect direct solar radiation.
