Cannon Fenske Direct Flow Viscometer as per BS/IP/CF and Astm D446 - Calibrated
The Cannon-Fenske Direct Flow Viscometer (also known as Cannon-Fenske Routine Viscometer) is a type of glass capillary viscometer used for accurately measuring the kinematic viscosity of transparent Newtonian liquids. It operates based on the principle of measuring the time it takes for a fixed volume of liquid to flow through a precisely calibrated capillary tube under gravity.It is majorly used in chemical and petroleum industries, to determine viscosity of a sample at different temperatures.
