Description
Cannon-Fenske viscometer BS 188 / IP 71, No. 150 is a calibrated capillary instrument for kinematic viscosity measurement of transparent liquids in the range 7–35 mm²/s. With capillary constant K 0,035, size No. 150 enables precise efflux timing under controlled bath temperature in accordance with BS 188 and IP 71. The design is intended for clear samples where the meniscus remains visible throughout the flow path. Supplied as 1 pc with a net weight of 0,079 kg, it supports routine analytical and industrial laboratory work on oils, solvents and other transparent fluids within this measuring window. This Cannon-Fenske type from manufacturer Witeg is calibrated for comparative testing and quality-control checks against British Standard and Institute of Petroleum procedures. It is used together with thermostatic viscosity baths and timing equipment typical of kinematic viscosity workflows. Compact glass construction facilitates careful handling and cleaning between samples while maintaining the capillary geometry needed for reliable determinations on transparent liquids in the stated range.

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.
