Automated and precise determination of direct kinematic viscosity at 40 °C or 100 °C*

  • Provides true kinematic viscosity measurement without the need to correlate dynamic viscosity data
  • Viscosity range:
    • Standard range tube provides viscosities from 10 mm²/s (cSt) to 700 mm²/s (cSt) at 40 °C and 5.5 mm²/s (cSt) to 200 mm²/s (cSt) at 100 °C
    • Low range tube provides viscosities from 2 mm²/s (cSt) to 140 mm²/s (cSt) at 40 °C and 100 °C
  • Follows ASTM D7279 and offers near ASTM D445 precision due to exceptional temperature control (±0.05 °C)
  • Rapid cycle time of 3 to 5 minutes from sample injection to test result

Portable, self-contained and dependable

  • Weighs approximately 10 lb and takes up less space than a coffee maker
  • Does not require a PC or any external utilities
  • Optional power inverter enables the instrument to run off of a 12 Vdc vehicle charging port
  • Rugged, reliable design has only two moving parts

Simple & safe operation

  • Graphical touch screen display provides step by step test instructions
  • Factory calibrated; no switches, gauges, or valves to adjust
  • Solid-state bath eliminates need for liquid bath
  • Intrinsically safe unit operates on 12 Vdc power
  • Optional printer available


  • Low cost of ownership
  • Requires only 10 mL to 15 mL of solvent and 0.5 mL of sample per test
  • No sample vials required; sample is injected directly into the instrument

*The unit can store two temperatures and is pre-calibrated to 40 °C and 100 °C but custom calibration at any two temperatures between 40 °C and 100 °C is available on request
