A refractometer (or brix meter), is an analytical instrument that uses a high-resolution optical sensor to measure the total reflection of a light beam that is in contact with a sample.

Laboratory refractometers serve as sophisticated devices designed to measure the refractive index of a sample with exceptional accuracy. They operate based on the principle of total internal reflection, utilizing prisms, lenses, and light sources to analyze the behavior of light as it interacts with the sample.

Laboratory Refractometers: These are precise instruments that are commonly used in scientific and industrial applications. They are used in gemmology for identifying gemstones based on their refractive index and in the pharmaceutical industry for measuring the concentration and purity of raw intermediate and final products.

Refractometers measure the change in the angle of light as it enters a transparent liquid or solid substance. Refractometers are commonly used to identify a material, determine its purity, or indicate the amount of a dissolved substance that it contains.

Refractometers are used as universal detectors in the investigation of liquids. They are an integral component of food analysis. For example, refractometers are ideally suited to investigate oils or fat, sugar, and sugar-containing substances.
