Abstract: An apparatus that is able to measure a viscosity and a density directly within a short time with a small amount of sample, which has been difficult for existing vibratory viscometer. The end part of an oscillator is formed in a shape, such as a sphere, whose resistance by a fluid can be logically derived, and the viscosity and the density of a fluid are calculated based on a predefined mechanical impedance and on an amplitude ratio and a phase difference of accelerations in the cases the oscillator is in the air and is in the fluid.
