Abstract

L'invention concerne un calorimètre du type à détection de flux thermique. Dans l'enceinte étanche 1 du calorimètre, deux compartiments distincts sont définis par un ensemble porte-cellule comprenant les cellules proprement dites 6 et 7, un puits annulaire 8 et une couronne 9 de suspension de l'ensemble à l'enceinte. Pour détecter un flux thermique entre les deux cellules, on utilise des piles thermo-électriques supportées par des tubes amovibles dans lesquels s'engagent les cellules. Application en calorimétrie et notamment pour des analyses thermiques.
