Description
The ASTM D445/D446 viscometer is a calibrated three-legged capillary instrument for determining the kinematic viscosity of transparent liquids in the measuring range 2–10 mm²/s. It corresponds to size No. 1 with a viscometer constant K of 0,010 and is adjusted for use according to ASTM D445 and D446 as well as ISO 3104 and ISO 3105. Approximate length is 283 mm, allowing secure placement in standard viscometer holders during flow-time measurements. Designed for transparent fluids only, the unit supports routine laboratory determination of kinematic viscosity under controlled thermal conditions. This instrument from manufacturer Witeg is supplied calibrated to maintain a defined capillary geometry for consistent analytical work. Pack size is 1 pc, with a net weight of 0,077 kg. It is suited to quality-control and research settings where clear liquid samples fall within the stated viscosity interval. The three-legged form factor aids stable mounting and handling through filling, equilibration, and measurement steps while protecting the adjusted measuring path required for reliable results.

Questions about Viscometer ASTM D445-446 2-10mm²/s
What is this article?
Viscometer ASTM D445-446 2-10mm²/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.
