Description
Viscometer ASTM D445 and D446 is a three-legged capillary instrument for kinematic viscosity determination of transparent liquids in the higher range 600–3000 mm²/s. It is fitted with capillary number 3C and constant K 3,0, aligned with the dimensional and procedural framework of ASTM D445 and D446. Approximate length is 283 mm, providing a practical size for thermostatic bath work and laboratory handling. The glassware is delivered uncalibrated, leaving calibration under the user’s quality procedures prior to quantitative use. Designed for transparent fluids only, the three-leg form factor supports secure positioning during sample introduction and efflux measurement. This variant from manufacturer Witeg comes as a single piece with a net weight of 0,07 kg and is appropriate for laboratories that need a higher-viscosity capillary class for oils, concentrates or other clear samples within the stated window. Capillary number, K value and measuring range are stated explicitly so the instrument can be matched to method and sample viscosity without invented grades, certifications or performance claims.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about Viscometer ASTM D445 446 600-3000
What is this article?
Viscometer ASTM D445 446 600-3000 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.
