miniQV®-X Single-Bath Kinematic Viscometer

For Rapid Kinematic Viscosity of Transparent and Opague Liquids with Near ASTM 445 Precision

ASTM D446 and ISO 3105

miniQV®-X is a fully automated, single-bath, benchtop viscometer for rapid kinematic viscosity measurement of transparent and opaque liquids with ASTM D445 precision capability. A 25-position sample handler allows unattended processing. The fast-run tube covers a 10-fold viscosity range between 5 mm²/s (cSt) and 800 mm²/s (cSt) from 40 °C to 100 °C. The miniQV-X has been optimized for condition monitoring of used oils.

Common Applications

  • In-service oil viscosity
  • Used oil analysis
  • Fleet maintenance
  • Condition monitoring

Compact, robust design

  • Temperature range: ambient to 100 °C (± 0.01 °C)
  • Kinematic viscosity range:
    • 5 mm²/s (cSt) to 800 mm²/s (cSt) in 10-fold increments at 40 °C
    • 5 mm²/s (cSt) to 50 mm²/s (cSt) in 10-fold increments at 100 °C
  • Fits in roughly the same benchtop area as an analytical balance
  • A well tested CANNON viscometer platform offers reliability and dependable support

High speed analysis

  • Analysis time: typically 3 minutes or less per test
  • 25-position removable sample handler provides unattended operation
  • Follows most ASTM D445 principles but with shorter flow times to accommodate rapid analysis

Fully automated benchtop testing

  • Affordable alternative to labor-intensive manual KV testing
  • Automates labor intensive tasks of sample measurement and viscometer tube washing and drying
  • Single PC manages up to 4 instruments using VISCPRO® software

Reduced consumable costs

  • ASTM D446/ISO 3105 fast run Ubbelohde-style tube reduces solvent usage/disposal costs
  • Low sample volume requirement of just 4 mL to 5 mL per test and solvent consumption of just 8 mL per test
  • Uses disposable, low-cost HDPE sample vials

Simplified maintenance & test versatility

  • Modular bath for easy maintenance access
  • Operators replace tubes in minutes, eliminating the need to schedule related service calls
  • Single-point temperature calibration avoids tube recalibration costs and maximizes test flexibility
  • Standard dual solvent input
