Description

Permit measurements of liquids whose meniscus cannot be seen at the timing marks when using 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 D 2170
• 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
• Upper bulb may be used for determining the degree of non-Newtonian behavior of the sample

Compliance

Specifications conform to ASTM D 446 and ISO 3105 for single determinations of viscosity for opaque liquids
