Baumé scale

Degrees Baume and Baume ( unit symbol ° Be ) is a French chemist Antoine Baume after ( 1728-1804 ) named, mostly outdated graduation of Aräometerskala to determine the relative density of liquids on the lift.

In the Baume scale is the lower fixed point ( 0 ° Be ) by the depth of immersion in water, and the upper by immersion in sulfuric acid monohydrate (66 ° Be ) at a temperature of 15.6 ° C, respectively defined. The distance between the two fixed points is divided on a paper scale in the stem of the hydrometer into 66 equal length segments. When determining the scale a 10% saline was used as a third fixed point, the density of 10 ° Be has been set.

In the confectionery industry and in the production of sugar coated with sugar coating the scale division is used in Baume today.

In addition, there were also slightly different scales, always based on the specific weight:
