Summary

A CALORIMETER IS DESCRIBED IN WHICH THERMAL CONTACT WITH THE SAMPLE IS MADE VIA A GREASE FILM. RADIATION SHIELDS BUILT INTO THE CALORIMETER MINIMIZE THE EFFECT OF TEMPERATURE GRADIENTS. USED IN AN ADIABATIC SHIELD SYSTEM THE APPARATUS GIVES RESULTS OF HIGH PRECISION AND ACCURACY. AN ALL-METAL WATER TRIPLE POINT CELL CAN BE INSTALLED IN PLACE OF THE SAMPLE TO CHECK THE TEMPERATURE MEASURING EQUIPMENT. EXPERIMENT SHOWED THAT A SINGLE CONTROLLED ELEMENT IS SUFFICIENT FOR DISCONTINUOUS HEATING CALORIMETRY. THE APPARATUS COULD BE RUN IN BOTH CONTINUOUS AND DISCONTINUOUS HEATING MODES.
