Vinometer, for the measurement of the mash alcohol level
A hydrometer is very inaccurate for alcohol concentrations that are less than 20% ABV. A vinometer is better suited to this range. While the vinometer does not show the right alcohol content precisely like a hydrometer, unlike a hydrometer it can also be used for liquids with extract and sugar content (wine, mashes, most, beer, starch). Measurements are also possible during fermentation. In addition, the measuring process is very simple and only takes a few seconds. Approximately 1-3 ml of the liquid to be measured is required for a measurement.
