CANNON® CAV® 4.1 is a fully automated, single bath, benchtop viscometer with two 14-position sample handlers for unattended D445 processing. Each of the two tubes covers a 100-fold viscosity range at values between 0.5 mm2/s (cSt) and 10,000 mm2/s (cSt) from 40 °C to 150 °C (down to 20 °C with optional integral bath cooler).
The CAV 4.1 replaces CANNON's trusted, obsolete CAV-2100 viscometer.
Conforms to ASTM D445/446. Common applications include formulated oil analysis, hydraulic oil analysis, additive analysis, marine fuel testing, base stock analysis, light and heavy fuel testing, waxes/paraffin, crude oil testing, and glycols/polyols.
D445 precision in a modern, dependable design
- Standard temperature range: 40 °C to 150 °C (down to 20 °C with TE bath cooler option)
- Viscosity range: 0.5 mm²/s (cSt) to 10,000 mm²/s (cSt) in 100-fold increments* (easily covering the range of 5 separate manual glass viscometers)
- Two fully accessible, 14-position sample handlers ensure reliable, unattended processing of up to 24 determinations per hour
- Removable carousels
- Automation provides an alternative to labor-intensive manual testing and reduces operator to operator variability
- A trusted CANNON viscometer platform offers reliability and dependable support
Compact & self-contained with flexible configuration
- Simple, out-of-the-box installation
- 35% smaller footprint than CAV-2000 series, conserves lab space
- Onboard computer permits running pre-programmed test parameters to be run without an external PC
- VISCPRO PC software enables programming of user-defined test methods and permits one PC to manage and control up to four instruments
- View, print, save, and export user-configurable reports
Reduced consumable costs
- Next generation Atlantic-style tubes reduce solvent usage and disposal costs by 50% over larger predecessor tubes
- Automated vial washing and drying enables reuse and reduces vial consumption
Simplified maintenance and test versatility
- Modular chassis design for easy maintenance access
- Operators can physically replace tubes in minutes, eliminating the need for related service calls
- Colored status indicator bath lights provide a simple indication of operational status
- Run multiple predefined/user-defined test methods within the same sample tray
- High throughput with optional sample preheating, capable of reaching 135 °C
- Instrument includes standard dual-solvent input
*Some upper viscosity measurements may be limited by test temperature and sample type. Ubbelohde-style tubes (for volatile products that are not a pure solvent and high melt waxes) are also available in 100-fold increments and fast run 10-fold increments from 0.5 mm²/s (cSt) to 10,000 mm²/s (cSt).
