Description
511 20 Cannon-Fenske reverse-flow viscometer is a calibrated glass capillary instrument intended for manual viscosity measurements. This model carries capillary number 200 and a viscometer constant K = 0,1, which together define its place in the Cannon-Fenske Steigrohr series. The instrument enables laboratory determination of kinematic viscosity by manual observation of flow time through the calibrated capillary. It is supplied as a single piece with a net weight of 0,275 kg and belongs to the 511 family of reverse-flow viscometers. Manufactured by SI Analytics - a Xylem brand, the 511 20 is suitable for analytical and quality-control laboratories that require a size-200 capillary with the stated constant. Calibration for manual measurements allows the constant K = 0,1 to be used directly in viscosity calculations under controlled conditions. The reverse-flow (Steigrohr) configuration is characteristic of Cannon-Fenske instruments employed for transparent Newtonian liquids. Capillary number 200 and K = 0,1 identify this particular size, facilitating correct selection according to the sample viscosity range. Of German origin, the unit is ready for use in established manual viscometry procedures.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 511 20, Cannon-Fenske reverse flow viscometer, calibrated for manual
What is this article?
511 20, Cannon-Fenske reverse flow viscometer, calibrated for manual is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand 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.
