The invention relates to a method and to a device for measuring, e.g. the viscosity of a fluid, by means of a rotating cylinder immersed in the fluid and on the basis of a torque applied to the cylinder and the cylinder's speed of rotation. The rotary cylinder (50) is completely immersed in the fluid contained in a tube (40) which is itself placed inside a constant temperature jacket (38) and is rotated by a rotating electromagnetic field produced by an induction winding (64) coaxially surrounding the tube and the cylinder and powered with alternating current at an adjustable predetermined intensity. The invention is applicable to measuring the viscosity of biological fluids, such as blood.
