Description
Viscometer ASTM D445/446 with measuring range 1,2–10,0 mm²/s is a three-legged capillary instrument for kinematic viscosity determination of transparent liquids. It is fitted with capillary number 1, constant K 0,01 and an approximate length of 283 mm. Uncalibrated glass construction supports standardised flow-time work according to ASTM D445 and D446 in petroleum, chemical and materials laboratories. The three-limb form is suited to immersion viscosity baths, assisting filling, thermal equilibration and timing of transparent sample fluids across a mid-low viscosity window. Supplied as one piece from manufacturer Witeg, the instrument is intended for quality control and research where users apply laboratory-specific calibration as needed. With net and gross weight of 0,072 kg each, it remains practical for routine bench and bath handling. The specified range of 1,2–10,0 mm²/s covers transparent media frequently analysed in everyday viscosity testing. Compact length fits common bath configurations used for capillary viscosity methods.

Questions about Viscometer ASTM D445 446 1.2-10.0
What is this article?
Viscometer ASTM D445 446 1.2-10.0 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.
