SR-4683 High Shear Rate and High Temperature Viscosity Tester by TBS Viscometer

SR-4683 Viscosity Tester by TBS conforms to ASTM D4683 Standard Test Method for Measuring Viscosity of New and Used Engine Oils at High Shear Rate and High Temperature by Tapered Bearing Simulator Viscometer at 150 °C and ASTM D4741 Standard Test Method for Measuring Viscosity at High Temperature and High Shear Rate by Tapered-Plug Viscometer. The Taper Bearing Simulator (TBS) viscometer was developed to accurately measure the rheological properties of lubricants over a temperature range of 100°C to 150°C and a shear rate of 1.0·10⁶ s⁻¹. Besides automotive engine oils, TBS viscometer can also be used in many other applications including hydraulic oil, automatic transmission oil, gear oil, printing ink, shock absorber oil, etc.
