Description
Cannon-Fenske viscometer 1,6-8,0 is a capillary instrument for determining the kinematic viscosity of opaque media. Built to the Cannon-Fenske design, it uses capillary no. 75 and covers a measuring range of 1,6–8 mm²/s, with a viscometer constant K of 0,008 mm²/s². Overall length is 295 mm, which supports convenient immersion and handling in a temperature-controlled bath during timed flow measurements. This configuration is intended for samples that are not optically clear, where reverse-flow or opaque-media Cannon-Fenske geometry is required for reliable timing of liquid passage through the capillary. Offered as a single piece from manufacturer Witeg, the unit suits routine laboratory viscosity work in quality control, process monitoring and research settings that need defined capillary size and constant within the stated range. The combination of capillary number, constant and measuring interval allows operators to select an appropriate tube for fluids whose kinematic viscosity falls between 1,6 and 8 mm²/s, supporting reproducible comparative measurements under standardised thermal conditions without optical observation of the meniscus through the sample itself.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about Viscometers Cannon Fenske 1.6-8.0
What is this article?
Viscometers Cannon Fenske 1.6-8.0 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.
