ABSTRACT A calorimeter bomb which has a housing made of a stainless steel body in which is formed a combustion chamber and a close fitting copper sleeve which equalizes the temperature of the housing. The temperature change of the bomb caused by the combustion of a sample in the chamber is measured by means of sensors between the body and the sleeve. The bomb is located in a static thermal enclosure and optionally is cooled by means of a Peltier element. The essence of the invention lies in the fact that the temperature of the housing is measured directly by means of the sensors, as opposed to the prior art method of measuring the temperature of the water in a jacket wherein the housing is immersed. This feature reduces the thermal inertia of the system and so the time needed for a calorific determination is reduced.
