Description
509 03 Ostwald viscometer is a classic capillary instrument supplied not calibrated, with constant K = 0,004. It is designed for laboratory viscosity work based on the Ostwald measuring principle, in which liquid flow time through a defined capillary is used to assess kinematic viscosity under controlled temperature conditions. The specified constant K = 0,004 places this model in the lower-viscosity portion of the Ostwald range, supporting comparative and method-development measurements once the laboratory performs its own calibration as required. Delivered as 1 pc with a net weight of 0,275 kg, the viscometer suits routine bench use in research and quality-control environments. This 509 03 unit from manufacturer SI Analytics - a Xylem brand provides a straightforward Ostwald configuration without factory calibration, giving users flexibility to calibrate according to their internal procedures and reference standards. Ostwald viscometers remain a practical choice for transparent liquids when simple capillary geometry and a known constant are needed for viscosity characterisation.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 509 03, Ostwald viscometer, not calibrated, constant K = 0.004
What is this article?
509 03, Ostwald viscometer, not calibrated, constant K = 0.004 is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand 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.
