CAV®-2100 Single-Bath Kinematic Viscometer

For Kinematic Viscosity of Transparent and Opaque Liquids
ASTM D445/D446, ISO 3104/3105, IP71

CAV®-2100 is a fully automated, single-bath laboratory viscometer with a 13-position sample handler for unattended D445 processing. Each of the two Atlantic-style tubes covers a 100-fold viscosity range between 0.5 mm²/s (cSt) and 10,000 mm²/s (cSt) from 20 °C to 150 °C (with available options).

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

Reliable D445 precision

  • Temperature range: ambient to 100°C (20°C to 150°C with available bath options)
  • Viscosity range: 0.5mm²/s (cSt) to 6,000mm²/s (cSt)* in 100-fold increments (easily covering the range of 5 separate manual glass viscometers)
  • Optional, environmentally friendly Peltier cooling requires no external refrigeration
  • A well tested CANNON viscometer platform offers reliability and dependable support

Fully automated laboratory testing

  • Fully visable 13-position sample handler ensures reliable, unattended processing of up to 24 determinations/hour
  • Automation provides an alternative to labor-intensive manual testing and reduces operator to operator variability

Test versatility

  • Two viscometer tubes housed within the single instrument bath enable a 10,000 fold viscosity range on a single instrument
  • VISCPRO® PC software enables one PC to manage and control up to four instruments
  • User-configurable reports may be viewed, printed, saved and exported
  • Various sample handling options including heated sample trays, glass and plastic vials and cups
  • A dual-solvent option is available

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