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. Designed for completely unattended operation, each CAV viscometer provides fully automatic kinematic viscosity testing within parameters specified by ASTM D 445.

The CAV-2100® features a single-bath modular construction with two viscometers per bath.
