A differential calorimeter includes a reference cell (1), a sample cell (2), a thermal shield (9) surrounding the reference cell (1) and the sample cell (2), a heating device (3, 4) thermally coupled to the thermal shield (9), a temperature sensor (14) for monitoring a temperature of the thermal shield (9), a temperature sensor (12) for monitoring a temperature differential between the thermal shield (9) and the cells (1, 2), and a control system (6). The control system (6) has an output line connected to the heating device (3, 4), input lines to receive signals from the temperature sensors (12, 13), and is configured to generate on its output line an output signal which is a function of both the input signals received on its input lines.
