The Cannon-Manning Semi-Micro Viscometer measures kinematic viscosity of small samples of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is ~1 mL (sizes 400 through 600 may require additional sample). Minimum bath depth is 200 mm (8 in). This is a calibrated viscometer which include a certificate of calibration and instruction sheet. Uncalibrated viscometers are also available.
