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.
