CANNON-Ubbelohde Viscometer
ASTM D445, ISO 3104
The Cannon-Ubbelohde Viscometer, with a more rugged design than standard Ubbelohde viscometers, is a suspended level viscometer for measurement of kinematic viscosity of transparent Newtonian liquids according to ASTM D 445 and ISO 3104. Also used for evaluating jet and hydraulic lubricants. Especially suited for use at temperatures above 93 °C (200 °F) or below –18 °C (0 °F). Require no kinetic energy corrections over 0.5 to 100 000 centistokes range.. Minimum sample volume is 11 mL. Minimum bath depth is 254 mm (10 in) but it must be submerged to 220 mm (8.5 in). Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
