Description
509 04 Ostwald viscometer is a capillary viscosity instrument supplied not calibrated, with constant K = 0,01. It follows the classical Ostwald design for determining kinematic viscosity from measured flow times under stable temperature conditions in the laboratory. The constant K = 0,01 defines the working range of this model within the Ostwald series and supports subsequent user calibration to local reference methods. Provided as 1 pc with a net weight of 0,275 kg, the unit is suitable for everyday viscosity work in analytical, research, and quality-control laboratories. Model 509 04 from manufacturer SI Analytics - a Xylem brand offers an uncalibrated Ostwald configuration that laboratories can qualify according to their own protocols and standards. Ostwald viscometers are valued for clear capillary geometry and straightforward handling when characterising transparent liquids. With constant K = 0,01, this instrument addresses a mid-low viscosity segment and complements other Ostwald sizes used for broader method coverage and comparative testing.
This article is part of Viscometers, in Density & viscosity measurement.

Questions about 509 04, Ostwald viscometer, not calibrated, constant K = 0.01
What is this article?
509 04, Ostwald viscometer, not calibrated, constant K = 0.01 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.
