The Cannon-Ubbelohde Viscometer, with a more rugged design than standard Ubbelohde viscometers, measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. 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). This is a calibrated viscometer which include a certificate of calibration and instruction sheet. Uncalibrated viscometers are also available.
