CALORIMETER WITH STABILIZED TEMPERATURE

The invention relates to a calorimeter including at least one measurement sensor (4) for receiving at least one sample, and at least three stages (1, 2, 3) for controlling the temperature, with decreasing size, each including a mounting (10, 20, 30) and means for controlling the temperature, the sma...

description The invention relates to a calorimeter including at least one measurement sensor (4) for receiving at least one sample, and at least three stages (1, 2, 3) for controlling the temperature, with decreasing size, each including a mounting (10, 20, 30) and means for controlling the temperature, the smallest stage being associated with said at least one sensor (4), in which: a first stage (1) also includes a screen (11) forming a first enclosure with the mounting (10) of said first stage; a second stage (2) is placed inside (12) said first enclosure and the mounting (20) thereof is thermally coupled with the mounting (10) of the first stage by first thermal conductances (23) comprising Peltier elements; and a third stage (3) is placed inside the second enclosure defined by the second stage and is thermally coupled with said second stage (2) by second passive thermal conductances (33) defining an adapted time-constant value.
