FIELD: acoustic engineering; catalysis tests, adsorption and corrosion processes. SUBSTANCE: device has two controlled generators, four controlled phase shifters, four ultrasonic inverters, correction unit, series-connected controlled amplifier, phase detector, integrator, analog-to-digital converter, monitoring and control unit connected to controlled inputs of all device components. EFFECT: high accuracy and informative capacity of measurement results; provision for detecting typical resonant frequencies of macrostructures of heterophasal system and for controlling physicochemical or elastic properties of specimens in desired direction by acting on them with set of standing waves at these frequencies. 1 dwg
