ABSTRACT:
The calorimeter comprises an external accommodating head (23) with two cavities (26, 27) which are capable of receiving a measurement cell (29), in which the specimen to be examined is inserted, and a reference cell (31); the cells (29, 31) are surrounded by a thermoresistor (229), the variation of the resistance of which is determined by a temperature variation, and a heater (129). The two cavities (26, 27) are closed by covers (35, 37) traversed by tubular stems (47-49) capable of supporting the cells (29, 31) for the insertion, into one of them, of a specimen contained in a tubular container (53), which is immersed in a chamber (29A) in which a fluid having high thermal conductivity is present; said cavities (26, 27) are reached by conduits (41, 43; 45) so as to be subjected to vacuum or to controlled pressure using replaceable gases (air, hydrogen, etc.).
