Baumé hydrometer. Sometimes referred to as a saccharometer, they are used to measure sugar saturations accurately in liquids. Useful for making sugar cane syrup. See: Sugarcane syrup at http://www.southernmatters.com/sugarcane/bulletins/cane_syrup.pdf

The Baumé scale was invented by Antoine Baumé (1728-1804), It is actually two scales, one for liquids that are more dense (heavier) than water and one for liquids that are less dense (lighter) than water. The hydrometers are calibrated using the rules on this site: Baumé scale at http://www.ilpi.com/msds/ref/baumescale.html

The scale is sometimes abbreviated 'Bé'. This scale is often used in industry to measure the concentration of acids, brines and pickling solutions. The measurement of salt solution concentration is employed in the processing of the dried salted meats charque and carne-de-sol. Brine solutions are important in the making of cheeses.

The Baumé scale is also used for tanning solutions in leather making and in taxidermy.
