Description
Viscometer ASTM D445 and D446 for the measuring range 1000–5000 mm²/s is a calibrated three-legged capillary instrument for kinematic viscosity determination of transparent liquids. Adjusted to ASTM D445 and D446 as well as ISO 3104 and 3105, it carries size designation Nr. 3B with viscometer constant K of 5,000. Approximate overall length is 283 mm, which suits standard laboratory immersion baths and timing procedures used in viscosity testing. The unit is calibrated to support reliable readings throughout the 1000–5000 mm²/s range. Supplied as one piece with a net weight of 0,081 kg, this glass viscometer from manufacturer Witeg is intended for analytical and quality-control work with clear fluids under method-compliant conditions. Its three-legged construction aids stable placement during measurement. The instrument integrates into established ASTM and ISO kinematic-viscosity workflows without geometric adaptation beyond the stated length and size class.

Questions about Viscometer ASTM D445 446 1000-5000mm²/s
What is this article?
Viscometer ASTM D445 446 1000-5000mm²/s 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.
