An apparatus used to measure the heat given off or absorbed in a chemical reaction
A device that can measure the energy deposited in it (originally devices to measure heat energy deposited, using change of temperature; particle physicists use the word for any energy measuring device )
An apparatus for measuring the amount of heat contained in bodies or developed by some mechanical or chemical process, as friction, chemical combination, combustion, etc
Device for measuring heat produced during a mechanical, electrical, or chemical reaction and for calculating the heat capacity of materials. A common design, known as a bomb calorimeter, consists of a reaction chamber surrounded by a liquid that absorbs the heat produced by the reaction. The amount of heat can be determined from the increase in temperature, taking into account the properties of the container and the liquid
In particle physics, any device that can measure the energy deposited in it by particles (originally a device that measured heat energy deposited, thus a calorie-meter) More Information: Liquid Argon Calorimeter, How does a Calorimeter Work?, Warm Iron Calorimeter
A heat-measuring device consisting of nested metal cups separated by an air space
