Description
Viscometer Cannon-Fenske 4000-20000, calibrated, is a capillary instrument for kinematic viscosity measurement of opaque media. It measures 295 mm in length, uses capillary no. 600, covers the measuring range 4000–20000 and has a viscometer constant K of 20,0 mm²/s². Designed to the Cannon-Fenske principle for non-transparent samples, it supports flow-time determinations on dark oils, heavy fluids and other liquids where optical meniscus reading is impractical. The unit is supplied as 1 pc(s), has a net weight of 0,139 kg and is delivered calibrated for direct laboratory use. This model from manufacturer Witeg is suited to temperature-controlled viscosity baths in quality control and research settings. With its higher capillary number and constant K of 20,0 mm²/s², it addresses more viscous opaque media while maintaining the reverse-flow geometry expected for standardized Cannon-Fenske work on undurchsichtige liquids in industrial and analytical laboratories.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about Viscometer Cannon Fenske 4000-20000 calibrated
What is this article?
Viscometer Cannon Fenske 4000-20000 calibrated 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.
