Description
Cannon-Fenske reverse-flow viscometer size 50 is a precision capillary instrument for kinematic viscosity measurement in the range 0,8–4 mm²/s with a constant K of 0,004. The reverse-flow (Steigrohr) design supports determinations on transparent and opaque liquids and is supplied with a factory calibration certificate. Compliance with ASTM D445, ASTM D446, ASTM D2515, ISO 3104 and ISO 3105 ensures suitability for standardised laboratory procedures in research and industrial quality control. Manufactured by Irmeco, this viscometer has a net weight of 0,1 kg and is delivered as a single piece ready for laboratory use. Size 50 covers the mid-low viscosity window, allowing accurate efflux timing under controlled temperature conditions. The instrument provides laboratories with a reliable tool for routine kinematic viscosity testing that aligns with the referenced international methods. Its compact form and factory calibration support consistent results across analytical workflows requiring documented capillary constants.

Questions about Viscometer
What is this article?
Viscometer is the article on this page. Luminix Health distributes Irmeco 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.
