 Principle:

- High temperature, high shear rate rotational (absolute) viscometry. - Tapered rotor turning at high speeds in very close tolerance to an identically matched tapered stator containing the sample. - Measures viscosity at multiple shear rates and temperatures which is particularly useful with multigrade oils and their influence on fuel efficiency.

Key Applications:

- Tests viscosity of organic and water-based fluids, including fresh & ‘used’ automotive and railroad engine oils, ATF’s, hydraulic fluids, inks, and polymeric solutions. - With use of associated cooling device, HTHS viscosities can be measured at temperatures ranging down to +40°C and viscosities up to 30 cP. - Fuel Efficiency Index, for determining viscosity-related fuel-efficiency contributions of engine oils. - Viscosity Loss Trapezoid, approach of appraising the total viscous influence of VI Improvers, synthetic fluids and their combinations when formulating engine oils.

Test Procedures (Specifications) - ASTM D4683, D6616, CEC L-36-A-90 - Equivalent to ASTM D4741 - SAE J300 Engine Oil Viscosity Grade Classification - API SL, SM, upcoming SN; Japan Classification JPI-5S-36-03 - ILSAC GF-2, GF-3, and GF-4, upcoming GF-5 Engine Oil Specifications

Operating Temperatures:

- Constant temperature control from 40°C to over 200°C (±0.1°C) with appropriate stator cooling.
