PCS USV (Ultra Shear Viscometer)

USV - Ultra Shear Viscometer

Accurate measurement of dynamic viscosity at very high shear rates is of particular concern in the automotive industry. Lubricants developed for motor vehicle applications are typically non-Newtonian making it necessary to reproduce the shear rate found in engines when measuring the viscosity.

Several international standards (ASTM, CEC) define procedures to measure the High Temperature High Shear (HTHS) viscosity at 150°C and 106 s-1.
