Cannon CAV 2000 Automatic Viscometer

Features

The CANNON CAV 2000 Series automatic viscometers are tabletop versions of the original CANNON Automatic Viscometer (CAV), the world’s leading automatic viscometer for more than three decades, used by most major companies in the petroleum industry. CAV 2000 Series instruments are now available in two models. The CAV-2100® features a single-bath modular construction with two viscometers per bath. The CAV-2200® features a dual-bath modular construction with a single viscometer in each bath. Most other specifications are identical for both models.

Capability

Designed for unattended operation, each CAV 2000 Series viscometer provides fully automatic kinematic viscosity testing within parameters specified by ASTM D 445. The CAV 2000 Series instruments measure flow rates within ±0.001 second by electronically timing the liquid meniscus as it moves between thermistor sensors. Bath temperature is controlled to an accuracy better than ±0.01°C at any selected temperature between 20°C and 100°C, and an accuracy better than ±0.03°C between 100°C and 150°C (high-temperature option required above 100°C), exceeding the precision requirements of ASTM D 445. Dark or opaque liquids may be measured with the same precision as transparent liquids.

Modularity

An outstanding feature of the CAV 2000 Series viscometers is modularity. A CAV 2000 Series instrument consists of: 1) one to four single- or dual-Bath Units, 2) a Service Unit (regulates vacuum/pressure and solvent flow), and 3) a Solvent Dispensing Unit for use with the customer’s pressureless solvent vessel. As many as four single- or dual-Bath Units may be connected to a single Service Unit and Solvent Dispensing Unit, and IBM®-compatible computer. A laboratory may begin operating with a single Bath Unit containing two viscometers, then add additional Bath Units as the work load increases. The Multi-Unit Interface Kit included with the CAV 2000 Series allows two, three, or four bath units to be connected to a single PC computer.
