Description
Cannon-Fenske viscometer 50,0-200 is a glass capillary instrument for kinematic viscosity determination of opaque media. Built according to the Cannon-Fenske principle, it is fitted with capillary number 300 and covers a measuring range of 50–200 mm²/s at a constant K of 0,25 mm²/s². Tube length is 295 mm, providing a practical format for immersion timing work in research, production control and teaching laboratories. The design is intended for undurchsichtige—opaque—liquids where reverse-flow measurement is preferred over clear-sample Ubbelohde-type tubes. Supplied as one piece with a net weight of 0,071 kg, the viscometer integrates into conventional constant-temperature baths and stopwatch or automated timing workflows. This instrument from manufacturer Witeg supports viscosity testing of darker oils, emulsions and similar non-transparent fluids across the stated range. It is a straightforward addition to laboratory glassware inventories focused on kinematic viscosity methods.

Questions about Viscometer Cannon Fenske 50,0-200
What is this article?
Viscometer Cannon Fenske 50,0-200 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.
