Shear Stability Tester

Shear Stability Tester

Application:

The Shear Stability Tester is an instrument used to determine an oils ability to retain its viscosity over a number of cycles of shear, or to evaluate the shear stability of polymer containing oils in terms of the permanent viscosity loss when a sample is subjected to mechanically stresses.
