Abstract: A fast reacting, automated calorimeter includes a reaction vessel (12) containing a chemically reacting mass, a fluid circulation system (14) containing heat transfer fluid, a portion of the system passing the fluid through an indirect heat exchanger (16) in the reaction vessel (12) for exchanging heat between the fluid and the reacting mass, a flow rate con­troller (24) responsive to variations in temperature of the reacting mass to vary the flow rate of the fluid circulated through the reaction vessel, a flow rate signal generator (32) for generating a signal related to the varying flow rate of the fluid passing through the reaction vessel, and a circuit (34 through 95) responsive at least to the flow rate signal and which generates a heat flow signal related to instantaneous rate of heat exchange between the reacting mass and the fluid. Heat transfer is measured and the reaction is controlled by varying, during the course of the reaction, the flow rate of heat transfer fluid fed into the reaction vessel at a predetermined temperature.
