Cannon 9721-E53 CFOU- 50 Uncalibrated

This Cannon 9721-E53 CFOU- 50 Uncalibrated the kinematic viscosity of dark and opaque Newtonian liquids using a reverse-flow design. Therefore, it enables accurate measurements when the liquid meniscus cannot be observed at the timing marks. As a result, it effectively overcomes the limitations of routine Cannon-Fenske viscometers when handling opaque samples.

Moreover, this instrument complies with ASTM D445 and ISO 3104 test methods. In addition, it conforms to ASTM D446 and ISO 3105 specifications. Consequently, laboratories can apply this viscometer within standardized viscosity testing frameworks without adjusting existing procedures.

Furthermore, this model supports the measurement of cutback asphalts and road oils at 60 °C (140 °F) according to ASTM D2170. Thus, it covers a viscosity range commonly required in asphalt and petroleum analysis. Additionally, laboratories use this viscometer to study lubricating and hydraulic oils at low temperatures, especially when evaluating the effects of additives on fluid performance.

Notably, users can apply external pressure during measurement. Therefore, they can vary shear stress and shear rate to perform more advanced flow behavior analysis. Meanwhile, the uncalibrated configuration offers flexibility, since laboratories may carry out in-house calibration or select a calibrated alternative when required.

Finally, this viscometer integrates easily with constant-temperature bath systems. Moreover, optional holders ensure stable positioning during operation. As a result, testing conditions remain repeatable and reliable.
