SimpleVIS®+ Portable Viscometer with Active Cooling

For Direct Kinematic Viscosity of Transparent & Opaque Liquids with Near ASTM D445 Precision
ASTM D7279

Common Applications

  • Product chain of custody monitoring
  • Contamination checks
  • Point of use testing
  • Industrial lube blending
  • Packaging and distribution of petroleum products
  • Petroleum terminals
  • Remote used oil predictive maintenance
  • Power plant applications
  • Remote mining applications

SimpleVIS®+ is a single sample, portable viscometer with built-in active cooling for rapid temperature adjustment. With near D445 precision, it is easy to use, rugged and fast. Available viscometer tubes cover a viscosity range of 2 mm²/s (cSt) to 700 mm²/s (cSt) at two selected temperatures between 40 °C and 100 °C.

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
  • Cools from 100 °C to 40 °C in ~30 minutes
  • 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 provides step by step test instructions
  • Factory calibrated; no gauges or valves to adjust
  • Solid-state temperature control eliminates need for liquid bath
  • Intrinsically safe unit operates on 12 Vdc power
  • Optional printer available


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