Description
Ubbelohde viscometer 300-3000 mm²/s, calibrated is a DIN-type capillary glass instrument intended for kinematic viscosity determination of higher-viscosity Newtonian liquids. It features a printed constant and is aligned with ISO/DIN 3105, DIN 51502, BS 188 and KFT 60-100. Size designation Nr. IIIc specifies an inner diameter of 2,65 mm and a capillary constant K of 3, corresponding to the measuring range 300-3000 mm²/s. The four-limb construction enables reliable suspended-level measurement, sample conditioning and efflux timing under thermostatic control. Factory calibration allows kinematic viscosity to be derived directly from measured flow times for laboratory and industrial quality-control workflows. This calibrated Ubbelohde viscometer from manufacturer Witeg is supplied as a single piece and is appropriate for oils, lubricants and other fluids falling within the stated viscosity interval. Clear constant marking and standardized DIN geometry support reproducible, standards-based results when the instrument is used in accordance with the referenced methods.

Questions about Ubbelohde viscometer 300-3000mm²/s calibrated
What is this article?
Ubbelohde viscometer 300-3000mm²/s calibrated 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.
