Description
Three-limb viscometer ASTM D445 and D446 No. 3C is a calibrated glass instrument for kinematic viscosity measurement of transparent liquids in the range 600–3000 mm²/s. Adjusted to ASTM D445 and D446 as well as ISO 3104 and 3105, it carries size No. 3C with constant K 3,000 and an approximate length of 283 mm, making it suitable for standard viscosity baths and routine laboratory determinations. The three-limb design supports work on clear fluids where defined flow geometry and visual observation are required. Factory calibration underpins reproducible results for quality control, formulation and analytical applications. Supplied as one piece with a net weight of 0,08 kg, the unit is practical for dedicated measuring stations. This model from manufacturer Witeg addresses laboratories that need a specified size, constant and calibrated range for transparent sample matrices within 600–3000 mm²/s.

Questions about Viscometer ASTM D445 446 600-3000mm²/s
What is this article?
Viscometer ASTM D445 446 600-3000mm²/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.
