Thermal flux detection calorimeter - is designed for high precision measurement and has analysing and checking cells in sealed container well

摘要

The calorimeter has a detection assembly (1) which includes a thermal reference unit (7). The unit (7) is in the form of a disc pierced by two symmetric cavities (10, 11). The detection assembly also includes an analysing cell and a reference cell (6). These are arranged inside of each of the cavities. Each cell is suspended from the reference unit by an upper edge which is embedded in the disc. The calorimeter has a series of star connected thermo-couples (14, 15) arranged in the same plane. The thermo-couples is formed of dissimilar metal wires. Wires of one metal type are individually in contact on an interior flat base of the cell situated in the plane. Wires of the other metal type are on a plane face formed in the plane by a annular shoulder of the reference disc.
