The Cannon-Fenske Opaque Viscometer is a reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D445 and ISO 3104. It permits measurement of liquids whose meniscus cannot be seen at the timing marks when using a Cannon-Fenske Routine-type viscometer. Used to measure kinematic viscosity of liquid (cutback) asphalts and road oils at 60°C (140°F) in range of 30 to 6000 centistokes according to ASTM D2170. Also used to study lubricating oils at low temperatures when investigating the effect of various additives on lubricating and hydraulic oils. External pressure can be applied to vary shear stress and shear rate. Specifications conform to ASTM D446 and ISO 3105. Minimum sample volume is 12 mL. Minimum bath depth is 229 mm (9 in). Special constant viscometers are available at additional cost. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
