Cannon 9721-E68 CFOU- 300 Uncalibrated

This Cannon 9721-E68 CFOU- 300 Uncalibrated kinematic viscosity of dark Newtonian liquids. It uses a reverse-flow design for consistent results. Therefore, it works when the liquid meniscus is not visible. As a result, it overcomes 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 use it within standard 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 fits asphalt and petroleum laboratories. Additionally, laboratories apply it to 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, the uncalibrated design offers flexibility. Laboratories may calibrate internally or choose a calibrated option.

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