Baume Scale
Baume Scale
The Baume scale is commonly used in the United States to measure the density of liquids such as syrups, juices, and industrial chemicals. The scale is based on the principle that the density of a liquid is related to its concentration of solutes, and it measures the specific gravity of a liquid relative to the density of water. The Baume scale does not directly measure the concentration of a solution but measures specific gravity. The values obtained are compared with known values of specific gravity from a table that gives the correct concentration.
The Baume scale has two different scales: one for liquids that are heavier than water and one for liquids that are lighter than water. The heavier-than-water scale is used for liquids such as syrups, while the lighter-than-water scale is used for liquids such as alcohol.
The Baume scale is expressed in degrees Baume (°Bé), with the number indicating the density of the liquid. For example, syrup with a Baume reading of 30°Bé is denser than syrup with a reading of 20°Bé. Baume Hydrometer is calibrated accordingly with two scales to measure the specific gravity of liquids.
The Baume scale has many applications in different industries:
- In the food and beverage industry, it is used to measure the concentration of sugar and other dissolved solids in syrups, juices, and other products.
- In the pharmaceutical industry, it is used to measure the density of drugs and other chemical compounds.
- In the chemical industry, it is used to measure the concentration of acids, alkalines, and other solutions.
