Description
Cannon-Fenske viscometer BS 188 / IP 71, No. 300 is a calibrated capillary instrument for determining the kinematic viscosity of transparent liquids within the measuring range 50–200 mm²/s. The tube carries a capillary constant K of 0,25 and is designated size number 300 for mid-range viscosity work under BS 188 and IP 71. Supplied as one piece with a net weight of 0,068 kg, it is intended for temperature-controlled viscosity baths with suitable timing equipment. Laboratories performing quality control, method development or teaching can integrate this capillary into established Cannon-Fenske workflows. The design from manufacturer Witeg is specified for transparent fluids only and is delivered calibrated to support consistent comparative measurements. Its defined constant and range help operators select the correct tube for a given sample viscosity window, reducing trials with mismatched capillaries. When used with proper temperature control and timing, the No. 300 Cannon-Fenske tube provides a practical route to kinematic viscosity data according to BS 188 and IP 71 for laboratory benches that maintain multiple size series.

Questions about Viscometer CANNON BS188 IP71
What is this article?
Viscometer CANNON BS188 IP71 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.
