Description
Viscometer ASTM D445/D446 for the measuring range 6000–30000 mm²/s is a calibrated, three-legged capillary instrument for determining the kinematic viscosity of transparent liquids. It is adjusted in accordance with ASTM D445 and D446 as well as ISO 3104 and 3105, supporting standardised laboratory viscosity work. Size No. 4C carries a viscosity constant K of 30000 and an approximate overall length of 283 mm, giving a practical format for immersion in temperature-controlled baths. The three-leg geometry aids stable positioning while the meniscus of clear samples is observed. Supplied as 1 pc with a net weight of 0,084 kg, this model from manufacturer Witeg is intended for transparent fluids only and is delivered calibrated for the stated range. Typical use includes quality control and research laboratories that need repeatable kinematic viscosity data on oils, solutions and other clear liquids within 6000–30000 mm²/s under ASTM and ISO protocols. The instrument integrates into existing bath and timing workflows without additional size conversion.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about Viscometer ASTM D445 446 6000-30000mm²/s
What is this article?
Viscometer ASTM D445 446 6000-30000mm²/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.
