Abstract

A water bath accommodating a calorimetric bomb (2) for measuring the combustion heat of substances with the aid of a calorimeter. The inner tank (3) is enclosed by an outer container (5) forming a water jacket and is shielded from the environment. If several measurements are conducted subsequently, the water found in the inner tank (3) and heated above its initial value through the combustion process taking place in connection with a previous measurement can be at least partially transferred into the outer container (5) with a second or other succeeding measurement prior to conducting it so that at least a part of the combustion heat of the preceding measurement can be used for heating up at least the water jacket in the outer container (5) in connection with the next measurement. Consequently, energy for tempering the water in the water jacket and/or in the water bath can be saved.
