Viscositeitsnorm N ₁₀

Viscositeitsnorm N ₁₀ is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Viscometers, inside Density & viscosity measurement, in Instruments de précision.

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.

The category is Density & viscosity measurement. The sub-category is Viscometers. The catalogue is Instruments de précision.

Shelves beside this one are Hydrometers and Density meters & pycnometers.
