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.

  • Integrated Custom Control System with custom PCB Boards and built-in TBS Touch Software – Eliminates computer, DAQ Boards, and associated cabling.
  • Improved operating stability to varying lab environment conditions.
  • Built-in 40-position AutoSampler with auto single-injection mechanism.
  • Incorporates (10) easily replaceable Reference Oil containers (Quart, 1/2 Gal. or Gal.).
  • Custom LED lighting scheme based on operating condition. Innovative temperature control system – no external cooling bath for 80° operation.
  • Auto-monitoring of Waste Oil container with Overfill Alarm.
  • Remote data access with Ethernet connection.
  • Barcode reader compatible.
