Cannon Fenske Reverse Flow Viscometer

Measures viscosity of opaque or dark liquids using reverse flow timing in a capillary, ensuring accurate, repeatable results under controlled conditions.

Cannon Fenske Reverse Flow Viscometer

Cannon-Fenske Reverse Flow Viscometer as per Astm D446 for Transparent & Opaque liquids - Calibrated 

Cannon-Fenske Reverse Flow viscometers are used in various applications, including determining the viscosity of liquid asphalts and road oils, studying the effects of additives on lubricating oils, and other situations where opaque liquids need to be analyzed. It consists of a precisely calibrated capillary tube through which the liquid flows under gravity. The time it takes for the liquid to pass between two etched timing marks is measured.
