The oscillating disk viscometer is a high accurate viscometer for lower viscosity fluids and visco elastic ones, including liquids and gases. Such viscometers have been set up abroad. It was known that the viscometer could be used to measure fluid viscosities within 35 MPa, and 300 ℃ with higher accuracy. The paper describes an oscillating disk viscometer builded by ourselves, reviews its measuring theory, and reports some results of R152a within 60～100 ℃ and 2 5 MPa.
