bomb cal·o·rim·e·ter

an instrument for determining the potential energy of organic substances, including those in foods. It consists of a hollow steel container, lined with platinum and filled with pure oxygen, into which a weighed quantity of substance is placed and ignited with an electric fuse; the heat produced is absorbed by water surrounding the bomb and, from the rise in temperature, the calories liberated are calculated.

bomb calorimeter

A constant volume device which measures the heat released or absorbed by a substance during a chemical reaction, allowing the calorie content of the substance to be calculated.

bomb calorimeter

A small insulated chamber in which a carefully weighed sample of food can be burnt and the amount of heat derived from the combustion calculated from the measured rise in temperature. The device is used to measure the calorific value of various foodstuffs. See also CALORIE.

bomb calorimeter

a CALORIMETER in the form of a thick-walled container in which organic material is ignited by electricity, burned, and the heat generated measured. The instrument is used to estimate the energy content of materials per unit weight.
