V-2020 Rotational Viscometer

For Measuring Viscous Drag of a Liquid Against a Rotating Spindle

The CANNON® V-2020 viscometers are easy-to-use, affordable rotational viscometers for the determination of dynamic viscosity. they measure the viscous drag of a liquid against a rotating spindle. With available spindles, the low viscosity LV-2020 measures from 1 mPa·s (cP) to 2,000,000 mPa·s (cP) while the moderate viscosity MV-2020 measures from 100 mPa·s (cP) to 13,000,000 mPa·s (cP). Both instruments offer 18 selectable speeds ranging from 0.3 rpm to 100 rpm.

Versatile applicability

  • Viscosity range:
    • LV-2020 model: 1mPa·s (cP) to 2,000,000mPa·s (cP), depending on the spindle* selected, for low viscosity materials, e.g. inks, oils and solvents
    • MV-2020 model: 100mPa·s (cP) to 13,000,000mPa·s (cP), depending on the spindle** selected, for moderate viscosity materials, e.g. creams, food and paints
  • 18 selectable spindle speeds ranging from 0.3 rpm to 100 rpm
  • Provides simultaneous measurement of viscosity and torque and determines rheological properties at different shear rates when material is tested with the same spindle at various speeds

Accurate and precise results

  • Torque measurement accuracy: ±1.0% of range in use
  • Repeatability: ± 0.2% of range in use

Easy to Use

  • Simple controls allow quick and easy selection of available spindle/speed options
  • Just select spindle/speed, turn on the viscometer and read the displayed viscosity
  • No calculation required. Viscosity data is automatically calculated and displayed in cP, P, mPa·s pr Pa·s
  • Keypad interface displays test control parameters (spindle/speed) and measured values (% torque, viscosity)
  • Front position bubble level enables convenient adjustment of vertical position
  • Auto range button automatically determines and displays maximum (100%) attainable torque viscosity for the selected spindle and speed

Low cost and transportable

  • Compact instrument transports easily in carrying case (included)
  • An economical choice for dynamic viscosity determinations

* Optional UL adapter is required to achieve 1mPa·s (cP) viscosities, included spindles measure to 15mPa·s (cP). 

** Optional RV-1 spindle is required to achieve 100mPa·s (cP) viscosities, included spindles measure too 400mPa·s (cP)
