Suspended level (Cannon Ubbelohde) 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). 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. Minimum sample volume is 11mL. Requires liquid bath depth of 254 mm (10 inches); must be submerged to approximately 220mm (8.5 inches).
