Abstract

An apparatus for the thermal measurement of the texture of a porous body, including a measuring head, a measuring assembly and a processing and control circuit. The measuring head is provided with two identical cylindrical cells, a measuring cell and a reference cell, arranged in a furnace. The measuring assembly measures the mean temperature of the measuring cell, and measures a calorific effect in the measuring cell, and includes a calorific effect detector, a calibration circuit, a temperature regulator including a furnace heater. The measuring circuit supplies a temperature signal and a calorific effect signal to the processing and control circuit, which in turn controls the heater.
