Description
Viscometer ASTM D445/D446 covering 10000–50000 mm²/s is a calibrated three-legged capillary viscometer for kinematic viscosity measurement of transparent liquids. Adjusted to ASTM D445 and D446 and to ISO 3104 and 3105, it provides a standardised tool for laboratory viscosity determination. Designated size No. 4B with viscosity constant K of 50000 and an approximate length of 283 mm, the instrument fits conventional temperature baths used in viscosity testing. The three-leg construction supports steady immersion while the flow of clear samples is timed. Offered as 1 pc at a net weight of 0,082 kg, this unit from manufacturer Witeg is calibrated for the 10000–50000 mm²/s window and is intended solely for transparent fluids. It suits quality-control and R&D environments that require consistent kinematic viscosity results on higher-viscosity oils, concentrates and other clear liquids under recognised ASTM and ISO methods. The compact glass format allows straightforward integration into existing timing and bath setups.

Questions about Viscometer ASTM D445 446 10000-50000mm²/s
What is this article?
Viscometer ASTM D445 446 10000-50000mm²/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.
