TBS 3000 HTHS Viscometer

High-Temperature, High Shear Rate Rotational (Absolute ) Viscosity

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 ‘true’ shear rate is calculated from known dimensions and speed of rotation. The TBS^® measures 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.
