Abstract: A sensor for differential calorimetric measurement including a thermometric cell and another cell, each cell including: a membrane of a low thermal conductivity material, having first and second surfaces; and a mechanism supporting the membrane, of a high thermal diffusivity coefficient material, in contact with the first surface of the membrane, the thermometric cell including at least two active thermometric elements located on the first surface of the membrane, the two cells configured to be assembled such that the second surfaces of the membranes of the cells are opposite one another, a sample and a reference used for taking measurement configured to be placed between the two membranes and directly in contact with the second surfaces, and at least one of the cells including a sealing mechanism opposite the first surface of the membrane, wherein a free space for a gas is arranged between the sealing mechanism and the membrane.
