The MetaCheck is an affordable metabolic analyzer that provides an accurate, professional metabolic rate measurement.  Measuring a person’s metabolic rate allows you to construct an effective weight loss plan based on individual caloric needs.  In the past, these measurements have only been available by using cumbersome, expensive equipment, and were generally only available at hospitals.  Today the MetaCheck provides the same critical data with just a simple 10 minute breath test at a fraction of the cost.  Plus, the MetaCheck is simple to use and maintain, using disposable testing supplies and requiring no additional computer to operate. Measured values show the thermophysical properties of the examined system or sample There are two bas ic types of calorimeters isothermal and adiabatic Constant temperature is sustained in t he isothermal calorimeter t means that the calorimeter is Differential Scanning Calorimetry APPLICATION Thermal Analysis of Lipsticks Utilizing DSC DSC 4000 For a complete listing of our global offices, visit www.perkinelmer.com/ContactUsCopyright Mr. . Dvorsky. SCH 4U1. A calorimeter is an object used for measuring the heat of a chemical reaction or physical change. . Can be as simple as a pair of cups and a thermometer, or as complex as a device attached to the Large Hadron Collider.. It operates under the law of conservation of energy (what is that?). Heat loss = Heat gained. A device used to measure the absorption or release of this heat is called . Calorimeter. Watch a video lecture for an example.. Quick Review of Concepts. We have been introduced to heat producing (. exothermic. ) reactions and heat using (. endothermic. ) reactions. Heat is a measure of the transfer of . energy. from a system to the surroundings and from the surroundings to a system. Fall, 2010 Indirect Calorimetry 1 Indirect Calorimetry Indirect Calorimetry CALORIMETRY The science that quantifies the heat release from metabolism is termed calorimetry . Figure 4.5 CALORIMETRY D Heat Capacity. Specific Heat Capacity (c): . the quantity of thermal energy required to raise the temperature of 1 g of a substance by 1°C.. Units are in J/g∙°C.
