Cannon 9721-F59 CFOC- 100 Calibrated

This Cannon 9721-F59 CFOC- 100 Calibrated kinematic viscosity of dark Newtonian liquids. It uses a reverse-flow design for dependable results. Therefore, it performs well when the liquid meniscus is not visible. As a result, it removes limits of routine Cannon-Fenske viscometers.

Moreover, this instrument follows ASTM D445 and ISO 3104 methods. In addition, it conforms to ASTM D446 and ISO 3105 specifications. Consequently, laboratories can apply it within standardized viscosity testing procedures.

Furthermore, this model supports testing of cutback asphalts and road oils at 60 °C (140 °F). It follows ASTM D2170 requirements. Thus, it suits asphalt and petroleum laboratories. Additionally, laboratories use it for lubricating and hydraulic oils at low temperatures. In particular, it helps evaluate additive effects on flow behavior.

Notably, users may apply external pressure during testing. Therefore, they can adjust shear stress and shear rate. This capability supports advanced flow analysis. Meanwhile, factory calibration at 40 °C ensures traceable results.

Finally, this viscometer integrates with constant-temperature bath systems. Moreover, optional holders ensure stable positioning. As a result, measurements remain repeatable and consistent.
