Since the (absolute) refractive index of the medium of interest as well as the refractive index of air depend on temperature, it is necessary to specify the details. Common variants are: the temperature-dependent refractive index of the medium relative to standard air, that is air at 20 °C, 1013 hPa, and 50 % relative humidity

Measurement of the refractive index of the test solution at 20 0C, using a refractometer, and use of tables correlating refractive index with soluble solids content (expressed as Sucrose), or direct reading of the soluble solids content on the refractometer. 1.6.2 Apparatus
Refractometers pass light through a food or beverage sample and measure the angle of refraction. Once the light passes through the reader, it measures the refraction — the angle that the light bends — and gives you the .Density and refractive index are routinely measured for quality control in the food and beverage industry, often to determine the Brix value of raw material and finished products. Although the designation “°Brix” is strictly valid only for pure sucrose-water solutions, in practice, the term as well as the methods of measurement are often .The refractive index is calculated from this critical angle. In addition, benchtop digital refractometers / brix meters use a built-in Peltier thermostat to control the temperature of a sample.
