Calorimetry is the measuring of heat quantities that are linked to biological, chemical or physical processes both exothermic as well as endothermic. IKA offers combustion calorimeters which are distinguishable by their operating modes: adiabatic, isoperibol, or "double-dry".

A combustion calorimeter measures the heat that arises from burning. The sample is weighed into a digestion vessel and filled with oxygen (30 bar). The burning process is started by means of an ignition spark. The experiment ends when the sample is fully burned. By measuring the temperature increase, the sample's calorific value or heating value can be calculated.

Calorimetry is used in many industries, including: food, construction material, raw materials, waste management, recycling, energy and synthetics.
