Measuring brix and percent acidity of a sudachi. Degrees Brix (symbol °Bx) is a measure of the dissolved solids in a liquid, based on its specific gravity, and is commonly used to measure dissolved sugar content of a solution. [1]
A rough conversion between specific gravity, SG, and either degrees Brix, Plato or Balling can be made by dividing the thousandths of SG above 1 (which is often referred to as gravity points) by 4. So a specific gravity of 1.048 has 48 gravity points, and 48 divided by 4 would be approximately 12 degrees Plato, Balling or Brix.
The Baumé scale is a pair of hydrometer scales developed by French pharmacist Antoine Baumé in 1768 to measure density of various liquids. The unit of the Baumé scale has been notated variously as degrees Baumé, B°, Bé° and simply Baumé (the accent is not always present).
These are to be used with the analysis methods that characterize sugars by refractometric means but find wide application outside the sugar industry as the sucrose polynomial is built into the firmware of modern refractometers and is the basis for calibration of purely optical refractometers which read in Brix.
A classical hand-held Brix refractometer. Brix (°Bx): Used in Italy, France, and Canada. Klosterneuburger Mostwaage (KMW): Used in Austria. The scale is divided into Klosterneuburger Zuckergrade (°KMW). However, the KMW measures the exact sugar content of the must. Normalizovaný moštoměr (°NM): Used in the Czech Republic, and Slovakia.
Brix refractometers are often used by hobbyists for making preserves including jams, marmalades and honey. In beekeeping , a brix refractometer is used to measure the amount of water in honey. Bausch & Lomb Abbe Refractometer, ca. 1919-1926
Refractometers are frequently used by grape growers and kiwifruit growers for Brix testing of sucrose levels in their fruit. Refractometry is also used in the gelatin industry. To convert the RI of a gelatin sol (reported in Brix) to a gelatin concentration, one need only multiply by eight-tenths (0.8). A sol with a 10.0 RI would therefore be 8 ...
On the previous IPTS-68 scale the densities [6] at 20 °C and 4 °C are, respectively, 0.9982041 and 0.9999720 resulting in an RD (20 °C/4 °C) value for water of 0.99823205. The temperatures of the two materials may be explicitly stated in the density symbols; for example: relative density: 8.15 20 °C 4 °C; or specific gravity: 2.432 15 0
