A refractometer is an optical precision instrument which determines the density of a liquid by the index of refraction.
This refractometer is a special model for beer brewers, and is used to measure the sugar content of the wort, as well as to follow the rinsing of the brewer's spent grains. Accurate, yet easy to use: simply place a few drops of liquid on the prism and the density is directly readable. There is no need for temperature correction due to automatic temperature compensation (ATC).
