CANNON-FENSKE OPAQUE VISCOMETERS

Reverse-flow type for dark liquids
Calibrated CFOC Series
Reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D 445 and ISO 3104. 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. Specifications conform to ASTM D 446
and ISO 3105. Provided with certificate of calibration and instruction sheet.

 

  • Minimum sample volume 12 mL. Require liquid bath depth of 229 mm (9 inches)

  • Size 25 has approximate constant 0.002 cSt/s and range of 0.4 to 2 cSt.

  • Viscometers with special constants are available by special order at additional cost

Uncalibrated CFOU Series
