Refractometer

Refractometer or refractometer is a laboratory tool commonly used to measure levels / concentrations of substances or solutes. For example sugar ("Brix"), salt ("Baume"), protein, etc. The working method of this refractometer utilizes the theory of light refraction. The concentration of the dissolved material is often expressed in units of Brix (%) which is the percentage of the dissolved material in the sample (aqueous solution). Dissolved substances are the total of all substances or ingredients in water, including sugar, salt, protein, acid, etc.
