miniAV® Single-Bath Kinematic Viscometer

For Kinematic Viscosity of Transparent and Opaque Liquids
ASTM D445/D446, ISO 3104/3105, IP 71

miniAV® is a fully automated, single-sample, benchtop viscometer for D445 testing. The Ubbelohde-style tube covers a 100-fold viscosity range at values between 0.5 mm²/s (cSt) and 10,000 mm²/s (cSt) from 15 °C to 100 °C (with available options). Meets ASTM D446/ISO 3105 requirements.

Common Applications

  • Formulated oil analysis
  • Hydraulic oil analysis
  • Additive analysis
  • Marine fuel testing
  • Base stock analysis
  • Light and heavy fuel testing
  • Waxes/paraffin
  • Crude oil testing
  • Glycols

D445 precision in a compact, robust design

  • Temperature range: ambient to 100°C (15°C to 100°C with available TE cooler)
  • Viscosity range: 0.5mm²/s (cSt) to 10,000mm²/s (cSt)* in 100-fold increments (easily covering the range of 5 separate manual glass viscometers)
  • Fits in roughly the same benchtop area as an analytical balance
  • Optional environmentally friendly Peltier cooling requires no external refrigeration
  • A well tested CANNON viscometer platform offers reliability and dependable support

Fully automated benchtop testing

  • Automation provides an alternative to labor-intensive manual testing and reduces operator to operator variability
  • Up to 12 determinations/hour
  • VISCPRO® PC software enables one PC to manage and control up to four instruments
  • User-configurable reports may be viewed, printed, saved and exported

Reduced consumable costs

  • ASTM D446/ISO 3105 Ubbelohde-style tube reduces solvent usage and disposal costs by 50%
  • Automated vial washing & drying enables reuse and reduces vial consumption

Simplified maintenance & test versatility

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

*Some upper viscosity measurements may be limited by test temperature and sample type. Fast run (10-fold range) tubes are also available.
