With our RHW-80 refractometer you can determine fast and exactly the alcohol content. The refractometer supplies the best results in alcoholic solutions or pure alcohols of all kinds (e.g. clear, grains, liquor). With liquids such as wheat beer, red wine becomes the result of measurement more inaccurately, because the refractive index becomes from the solved materials/float-openly/coloring materials falsifies. This problem can be solved by manufacturing a distillate of the liquid. Here some drops are sufficient .

Calibration: zero calibration with water at 20°C
