The BS/U-Tube Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is 7 mL (sizes A-C), 12 mL (sizes D-F), and 23 mL (sizes G-H). Minimum bath depth is 280 mm (11 in). Viscometers are provided with a certificate of calibration and instruction sheet. Holders are not available.
