Koehler K447 BX Dynamic Viscosity

alat laboratorium umum

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.
