A refractometer is an optical precision instrument which determines the density of a liquid by the index of refraction.

A refractometer instantly measures and displays sugar concentrations in fruit juices (wine) and wort (beer). The meter can be read easily and immediately. However, it is only suitable for measuring unfermented non-alcoholic solutions, not for fermenting wines or beers.
The alcohol refractometer is intended only for pure alcohol solutions. There is no need for temperature correction due to automatic temperature compensation (ATC).

A complete operation manual on the refractometers is available in 11 languages. Download it here.
