KOEHLER K447-SX Dynamic Viscosity by Sharp Series Rotational Viscometer

Test Method
Determines the dynamic viscosity of a substance by the rotation of a specified spindle within the sample at the speed giving the maximum torque reading on the viscometer. The resulting torque reading is used to calculate the viscosity of the substance.
