FIELD: measuring technique.
SUBSTANCE: method comprises preliminary measuring of frequency and attenuation coefficient of the vibration system without the specimen, filling the specimen into the thin-walled cell, measuring the values of frequency and attenuation coefficient of the system in the presence of the specimen, determining viscosity and shear modulus of the specimen by comparing the system vibration in the presence and in the absence of the specimen. The device comprises torsion pendulum made of inertia disk, flexible member, and specimen. The fluid specimen is set into the thin-walled cell. The first end of the cell is secured to the inertia disk, and the second end is connected to the unmovable base. The flexible member is made of a rubber cord that is perpendicular to the axis of vibration. The mid point of the cord is connected with the disk at the maximum distance form the axis.
EFFECT: expanded functional capabilities.
