A calorimeter is a device used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types. A simple calorimeter just consists ...
A heat meter, thermal energy meter or energy meter is a device which measures thermal energy provided by a source or delivered to a sink, by measuring the flow rate of the heat transfer fluid and the change in its temperature between the outflow and return legs of the system.
Heat meter uses a thermometer to measure rate of heat flow. Thermostats have used bimetallic strips but digital thermistors have since become popular. Alcohol thermometers , infrared thermometers , mercury-in-glass thermometers, recording thermometers , thermistors , and Six's thermometers (maximum-minimum thermometer) are used in meteorology ...
For every different way there is to experience heat — in the sun, in the shade, on a rock, in a glade — there is a scientific debate about how to correctly measure and assess it.
Heat generated by living organisms may also be measured by direct calorimetry, in which the entire organism is placed inside the calorimeter for the measurement. A widely used modern instrument is the differential scanning calorimeter, a device which allows thermal data to be obtained on small amounts of material. It involves heating the sample ...
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]
Thermopiles are used to provide an output in response to temperature as part of a temperature measuring device, such as the infrared thermometers widely used by medical professionals to measure body temperature, or in thermal accelerometers to measure the temperature profile inside the sealed cavity of the sensor. [4]
Thermopiles are used for measuring the intensity of incident radiation, typically visible or infrared light, which heats the hot junctions, while the cold junctions are on a heat sink. It is possible to measure radiative intensities of only a few μW/cm 2 with commercially available thermopile sensors.
