FIELD: examination and analysis of materials. SUBSTANCE: porosimeter has temperature- controlled vacuum cell for specimen being analyzed and test specimen. Temperature-controlled cell is provided with facility for measuring the electrical capacitance of test specimen connected to recorder. Porosimeter has also vacuum processing system with device which doses drying of specimens. Dosing device is essentially chamber with stop valves at its inlet and outlet or hydraulic resistor with stop valve is placed in thermostat at temperature higher than thermostat temperature for cell with specimens. EFFECT: higher results of analysis. 1 dwg
