hydrometer VINOFERM with 3 scales

The 3-scale hydrometer is ideal for checking wines, ciders, beers and honey. With three color scales: density, sugar content and potential alcohol content. Range: 0.990-1.150 SG 0-360 g / l of sugar. 0-20% alcohol by volume. Requires a 200 ml cylinder. Density measurement: Glass hydrometers follow the "Archimedes" principle: any object fully or partially immersed in any liquid experiences an upward force equal to the weight of the liquid placed around the object. A gram is the mass of 1 cubic centimeter (1 cm3 or 1 ml) of pure water. Some units are used to measure sugar, which have a direct relationship to the unit of mass. But other units are related to density or specific gravity. Relative density is the volume per unit volume (g/cm3). The specific gravity of pure water is 1 g/cm3. Sg of water is 1 (1000). The strength of wine is measured as follows: For example, the sugar content of wine before fermentation is +80 and -5 after. The formula for the alcohol content is: 85:7.5 =11.33% or based on the viscosity scale: at the beginning, e.g. 1.116 (16%) and at the end of fermentation 1.030 (4%), the alcohol content of the final product is 16-4=12%. The sugar content at the beginning and end must be added together and divided by 7.5. Or, for example, the juice shows the sugar content at 120g (+20C on the sugar scale) and viscosity 1.044 (on the scale), when the amount of sugar ferments the alcohol content is 6.1% (on the alcohol scale). If we want a wine with 14% alcohol content, and the sugar scale on the device shows that 270g of sugar per liter is necessary, but the measurement shows only 120g - therefore, we need to add sugar 270-120= 150g/l of sugar to the juice. What is a densimeter and why is it necessary? A hydrometer or densimeter is a gadget that measures the density of a liquid. This wort is used to measure the sugar content when brewing beer and beer. A densimeter is essentially a float with a scale on it. The scale shows how deep it sinks into the liquid and the reading is read from the water line. The result shows the ratio of the density of the liquid to the density of pure water. The density of pure water when measured with a hydrometer is always 1.000. If sugars or other soluble substances (for example, salt) are mixed into the water, we will get a reading higher than 1,000. However, the density of alcohol is generally lower than the density of pure water, so the reading of an alcohol-rich liquid is below 1,000. The readings of the densimeter are set for measurement in a liquid at 15 degrees (Celsius), so it is worth making sure that the liquid is more or less at this temperature at the time of measurement. A simple densimeter can be obtained from a store at a price of 5-15 euros. Densimeters are available with one and three scales. A single-scale densimeter only shows specific gravity. In addition to the specific gravity, the three-scale densimeter shows the sugar content in g/l and the potential alcohol content in the finished drink. For example, in the case of flounder, the densimeter reading should remain at the limit of 1020 on the specific gravity scale..
