CANNON-FENSKE ROUTINE VISCOMETER
ASTM D445, ASTM D2170, ISO 3104
The Cannon-Fenske Routine Viscometer measures kinematic viscosity of transparent Newtonian liquids, particularly petroleum products or lubricants, according to ASTM D445 and ISO 3104. Specifications conform to ASTM D446 and ISO 3105. Minimum sample volume is 7 mL. Minimum bath depth is 230 mm (8 in). Special constant viscometers are available at additional cost. Available as a calibrated viscometer (which includes a certificate of calibration and instruction sheet) or an uncalibrated viscometer. Holders are sold separately.
