Description
Cannon-Fenske viscometer 240-1200 is a glass capillary instrument intended for kinematic viscosity determination of opaque liquids across the measuring range 240–1200 mm²/s. Designed according to the Cannon-Fenske method for non-transparent media, it is equipped with capillary number 400 and a stated constant K of 1,20 mm²/s². These parameters support conversion of measured efflux times into kinematic viscosity under controlled temperature conditions. The tube length is 295 mm, suitable for standard laboratory viscosity baths and holders used with reverse-flow Cannon-Fenske geometry. Supplied as 1 pc(s) with a net weight of 0,065 kg, the instrument addresses quality control, process monitoring and research tasks involving higher-viscosity dark oils, process fluids or other light-absorbing samples. This model from manufacturer Witeg provides a defined capillary and constant for comparative work within the 240–1200 mm²/s window. Laboratories can apply familiar Cannon-Fenske opaque-media handling while covering the elevated viscosity band associated with capillary number 400.

Questions about Viscometer Cannon Fenske 240-1200
What is this article?
Viscometer Cannon Fenske 240-1200 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Lab instruments.
A capillary viscometer times the flow of a liquid through a tube. A rotational viscometer twists a spindle in the liquid. Both need a stated temperature. Kinematic and dynamic viscosity are different numbers. The capillary size has to put the flow time in the range the method allows.
Density is mass divided by volume. A hydrometer floats at a depth that depends on the density of the liquid. A pycnometer is a vessel of known volume that is weighed full. Viscosity is the resistance to flow. A capillary viscometer times how long a volume takes to fall through a tube. Both measurements need a stated temperature, because liquids change density and viscosity as they warm. The units trace to the BIPM and to NIST.
