红葡萄酒中乙醇含量检测方案(饮用酒检测仪)

数字式酒精度计测定智利红葡萄酒中的乙醇含量 应用资料这是一个关于智利红葡萄酒(中等酒体类型)中酒精度含量(vol%)、相对密度(t/t)和密度(g/cm3)的测定范例。高精度数字式酒精度计可用于确定葡萄酒酿造过程中的这些应用。技术说明: 酒精样品必须按照当地法规规定的程序蒸馏，然后才能使用数字式酒精计测量乙醇含量。KGM KYOTO ELECTRONICSMANUFACTURING CO.，LTD.APDA-02070v enLK-MKYOTO ELECTRONICSMANUFACTURING CO.，LTD.1/1 Application Note Determinationof alcohol content inChilean redwine(medium-bodied wine) by Alcohol meter Industry Food and BeverageInstrument Alcohol meterMeasurement method GB 5009.225， Resonant frequency oscillation 1.Scope This is an example about determination of the alcohol content (vol%)， specific gravity (t/t) anddensity (g/cm3) in Chilean red wine (medium-bodied type). The alcohol meter can be used enoughfor determination of these applications on the wine making process. Technical note： The alcohol sample must be distilled as per the procedure specified on localregulations before the alcohol content can be measured with this alcohol meter. 2. Apparatus ·Alcohol meter ALM-155 ·Distillation apparatus 3. Sample ·Chilean red wine (medium-bodied wine) 4.Reagent ·Pure water for rinsing 5. Procedure A： Alcohol content (vol%)： Take distilled sample solution into beaker Introduce the sampling nozzle into the beaker Press [Meas.] button on the instrument B： Specific gravity (t/t) and Density (g/cm)： Take wine sample solution into beaker Introduce the sampling nozzle into the beaker )Press [Meas.] button on the instrument 6.Measurement results Alcohol (vol%) at 20℃ S.G.
