Dichtheidshydrometer, zonder thermometer

Dichtheidshydrometer, zonder thermometer is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Hydrometers, inside Density & viscosity measurement, in Instruments de précision.

A hydrometer floats in a liquid and the stem reading is the density or a related scale such as Brix. The liquid has to be at the temperature printed on the stem, or a correction is required. A chip on the stem changes the reading. One hydrometer does not cover every density.

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 Hydrometers. The catalogue is Instruments de précision.

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