Description
Ubbelohde viscometer 100-1000 mm²/s, calibrated is a DIN-type glass capillary instrument for kinematic viscosity measurement of Newtonian liquids. The unit is supplied with a printed constant and follows ISO/DIN 3105, DIN 51502, BS 188 and KFT 60-100. Size designation Nr. III provides an inner diameter of 2,01 mm and a capillary constant K of 1,0, covering the measuring range 100-1000 mm²/s. Its four-limb design facilitates suspended-level operation, controlled filling and precise efflux timing in a temperature-controlled bath. Calibration supports straightforward calculation of kinematic viscosity from observed flow times in quality-control and analytical laboratories. This calibrated Ubbelohde viscometer from manufacturer Witeg is offered as one piece and suits applications involving medium-viscosity oils, process fluids and related samples within the stated range. Standardized DIN geometry together with the marked constant promote consistent, method-compliant results when the instrument is handled according to the referenced standards.

Questions about Ubbelohde viscometer 100-1000mm²/s calibrated
What is this article?
Ubbelohde viscometer 100-1000mm²/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.
