CAV 4.2 230 VAC, 50/60 Hz, 1200 watts - 1 unit

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

CAV® 4.2 is a dual-bath, benchtop viscometer with two 14-position sample handlers for unattended D445 processing. Each of the Ubbelohde-style tubes (one per bath) covers a 100-fold viscosity range between 0.5 mm²/s (cSt) and 10,000 mm²/s (cSt) from 15 °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

Features & Benefits

D445 precision in a modern, dependable design

• Temperature range: ambient to 100 °C (15 °C to 150 °C with available bath options)
• 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)
• 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 determinations per hour
• Optional environmentally-friendly Peltier cooling

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
• Single unit runs using the on-board computer, without need for an external PC, or a single PC manages up to 4 units using VISCPRO® software

Reduced consumable costs

• ASTM D445/ISO 3105 Ubbelohde-style tube design reduces solvent usage and disposal costs by 50%
• Automated vial washing and drying reduces vial consumption and replaces manual washing

Simplified maintenance and test versatility

• 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
• Colored status indicator bath lights provide a simple remote indication of operational status
• Multiple pre-defined/user-defined test methods can be run in the same sample tray
• High-throughput, selective zone heating preheats individual samples to any temperature from ambient to 100 °C
• 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.

Options

Factory installed options (see NOTE) must be specified when ordering. Part numbers are listed below for field installable options. Field installation must be performed by factory-trained personnel (unless indicated by an asterisk *). Field installation costs are not included.

Note: A third solvent input, integrated high temperature baths (left or right) and additional temperature calibration (for each temperature beyond the first) are also available at the time of ordering.
