Cannon 9721-E56 CFOU- 75 Uncalibrated

This Cannon 9721-E56 CFOU- 75 Uncalibrated kinematic viscosity of dark and opaque Newtonian liquids. It uses a reverse-flow design for accurate results. Therefore, it works well when the liquid meniscus is not visible. As a result, it solves a key limitation 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. It follows ASTM D2170 requirements. Thus, it fits asphalt and petroleum laboratory needs. Additionally, laboratories use it for lubricating and hydraulic oils at low temperatures. In particular, it helps evaluate additive effects on flow behavior.

Notably, users can apply external pressure during testing. Therefore, they can adjust shear stress and shear rate. This feature supports advanced flow analysis. Meanwhile, the uncalibrated design offers flexibility. Laboratories may calibrate it internally or choose a calibrated version.

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