About the Brix (%) Scale.

All Refractometers are designed to measure the refractive index of a solutoin. The Brix scale is based on a sucrose (sugar) and water solution. However, since most samples contain substances other than sugar - such as salts, minerals and protenis - the Brix percentage repesents the total concentration of all soluble solids in the sample. For certain samples, such as cutting oils and other industrial fluids, a conversion chart from the Brix percentage to the sample's total concentration may be necessary.
