The CANNON® CAV® 4.2 is an automated, high throughput, dual-bath viscometer for ASTM D445. The CAV® 4.2 combines CANNON® quality and reliability with modern design and unique features to enhance lab productivity, reduce costs, and improve data quality.

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 modern, dependable design

  • Temperature range: 20 °C to 100 °C (15 °C to 150 °C with available options)
  • Viscosity range: 0.5 mm2/s to 10,000 mm2/s in 100-fold increments
  • Dual, independent modular baths provide easy maintenance access and simultaneous testing at two different temperatures
  • Two independent, fully-accessible sample handlers ensure reliable, unattended processing of up to 24 tests per hour

Fully self-contained bench-top unit with flexible connectivity

  • Simple, out-of-the-box installation. No external components required
  • 35% smaller footprint conserves lab space
  • Professional installation, VISCPRO® data storage and management software, viscometer tubes, standards, and high precision digital thermometer are included with each instrument
  • A single unit can be run using the on-board computer, without need for an external PC, or a single PC can manage up to 4 units using VISCPRO® software

Reduced consumable costs

  • Tube design reduces solvent usage and disposal costs by 50%
  • Automated vial washing and drying reduces vial consumption and replaces manual washing

Easy change-out, versatile viscometer tubes

  • 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

Status indicator bath lights

  • Colored lights provide a simple remote indication of operational status

Flexible sample handling

  • Multiple pre-defined/user-defines test methods can be run in the same sample tray
  • High throughput selective zone heative preheats individual samples to any temperature from ambient to 100 °C.
