method and arrangement for differential pressure calorimetry

摘要

The method involves produces thermal compensation, using two measuring chambers as calorimeters (1,2), enclosed in a pressure-transmitting fluid (3), in a casing (4) controlled by a compressor or decompressor (9). The chambers are fitted with thermostats (10,11). The pressure is changed in the same way on a measuring probe (5) heated or cooled to the correct temperature and on a reference probe (6). An Independent claim is included for a device for implementing the method.
