Cannon 9721-F68 CFOC- 300 Calibrated

This Cannon 9721-F68 CFOC- 300 Calibrated kinematic viscosity of dark Newtonian liquids. It uses a reverse-flow design for reliable readings. Therefore, it performs well when the meniscus is not visible. As a result, it removes limits of routine Cannon-Fenske viscometers.

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

Furthermore, this model supports asphalt and road oil testing at 60 °C (140 °F). It follows ASTM D2170. Thus, it suits petroleum and materials laboratories. Additionally, researchers use it for lubricating and hydraulic oils at low temperatures. In particular, it helps study additive effects.

Notably, users can apply external pressure. Therefore, they may vary shear stress and shear rate. Meanwhile, factory calibration at 40 °C ensures traceable results.

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