Cannon-Ubbelohde Viscometers
Calibrated CUC (9721-K50) Series
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. Viscometer constant is same at all temperatures. Specifications conform to ASTM D 446 and ISO 3105. Read more about the significance of expanded uncertainty.
Provided with certificate of calibration and instruction sheet.
Uncalibrated CUU (9721-J50) Series
Similar to 9721-K50 series, but uncalibrated.
- Holder is not supplied. For holders, see 9726-M70, 9726-M73, and 9726-M76.
- Minimum sample volume 11 mL. Require liquid bath depth of 254 mm (10-inches); must be submerged to approximately 220 mm (8.5-inches).
