Cannon 9721-K74 Model CUC-400 Size 400 Cannon Ubbelohde Viscometer Tube, Calibrated. These viscometers are used 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). Requires 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. Minimum sample volume is 11mL. Requires liquid bath depth of 254 mm (10 inches); must be submerged to approximately 220mm (8.5 inches). Certificate of calibration and instruction sheet is included. Holders are sold separately.
- Range (centistokes): 240 to 1,200
