The High-Temperature and High-Shear Viscometer is mainly used to determine the apparent viscosity of lubricating oil at high temperature and high shear rate.
The test principle is to make the sample flow out from the capillary viscometer under the pressure of nitrogen (carbon dioxide) under the test condition of 150°C. By the outflow time and pressure of the sample, the apparent shear rate of capillary viscometer can be obtained to a certain apparent viscosity, with the viscosity of the oil corresponding to the measured pressure for the curve corrected with each viscometer cell.
