TBS 3000 HTHS Viscometer
High-Temperature, High Shear Rate Rotational (Absolute) Viscosity
ASTM D4683 | D6616
Reference Technique for ASTM D4741 and D5481
High-Temperature, High Shear Rate Rotational (Absolute) Viscosity: The coaxial Rotor/Stator design permits the exact measurement of rotor position and the torque response of the liquid’s resistance to flow (viscous friction), which determines the apparent fluid viscosity. Applying a constant and linear shear rate profile continually to the fluid makes the TBS an absolute viscometer where the ‘true’ shear rate is calculated from known dimensions and speed of rotation. The TBS measures the viscosities of fresh and used oils at multiple select shear rates and temperatures. This proves particularly useful with multi-grade oils and their influence on fuel efficiency.
Developed in 1979 and under several patents, the TBS Viscometer became the world’s first high shear viscometer. It remains the modern benchmark ‘referee’ instrument for HTHS viscometry due to its innovative measurement technique, robust design, and notable operational versatility.
This newest TBS model is completely redesigned and re-innovated providing multiple enhancements to electrical and temperature components, automation, calibrations, and oil injection features, dramatically improving the overall user experience. These advancements promote simplified operations and less reference oil usage with no separate components while offering the same or better precision and robustness as previous TBS models.
