Description
Viscometer ASTM D445 No. 2C is a calibrated, three-legged capillary instrument for kinematic viscosity measurement of transparent liquids in the range 60–300 mm²/s. Adjusted to ASTM D445 and D446 as well as ISO 3104 and ISO 3105, it carries size designation No. 2C and a capillary constant K of 0,300. Approximate length is 283 mm, supporting installation in standard viscosity baths. The single-piece unit has a net weight of 0,079 kg and is supplied calibrated for laboratory use. From manufacturer Witeg, this three-leg design suits transparent sample media in quality-control, research and teaching environments that follow ASTM or ISO capillary methods. Selection of the No. 2C size with K 0,300 aligns the tube to the 60–300 mm²/s window, helping operators match capillary and sample viscosity. When operated with appropriate temperature control and timing, the instrument supports routine determination of kinematic viscosity under the cited ASTM and ISO standards. Its three-legged construction and defined measuring range make it a practical addition to multi-size capillary sets covering adjacent viscosity intervals.

Questions about Viscometer ASTM D445 No. 2C 60-300mm²/s
What is this article?
Viscometer ASTM D445 No. 2C 60-300mm²/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.
