An apparatus for the measurement of liquid-shear impedance in the frequency range 11–170 kHz using a thin-walled nickel-tube resonator is described. The working principle of the method used has been previously published. Compared with the prototype the most important advances in the design concern the suspension of the resonator and complete automatization of the measurements and data handling. At the cost of not measuring at the fundamental frequency accuracy and ease of operation are greatly improved. Results for Newtonian and viscoelastic liquids are presented. Comparison with other types of apparatus is made.
