Alcohol concentration meter, also known as alcohol meter, ethanol concentration meter, alcohol tester, etc., is a precision optical instrument designed to measure the ratio of alcohol concentration in aqueous solutions such as liquor and industrial alcohol. Easy to use and competitively priced. The concentration of the solution can be read by simply dropping a few drops of liquid onto the prism and then looking at the light.
Liquor is a favorite drink. In recent years, some unscrupulous traders in some places in China have used violence to use industrial ethanol and water and alcohol to match the sale of white wine. Some even have similar properties to ethanol, and the price is lower. Water is pretending to be sold as white wine, which poisons people who buy and drink. Lightness causes vision loss, blindness in both eyes, and death in serious cases, causing heavy losses to people's lives and property. Therefore, solving the problem of quickly identifying ethanol and methanol has practical significance.
Key words: refractive index, ethanol, liquor, rapid identification,
China issued GB/T394.1-94 "Industrial Ethanol", GB 6820-92 "Industrial Synthetic Ethanol", GB10343-89 "Edible Alcohol" and GB298-92 "Industrial Methanol", GB/T394.2-94 " The alcohol test method, etc., specifies the ethanol content and the methanol content, and also specifies the measurement method. However, since the measurement of the methanol content requires equipment and reagents, and time-consuming, etc., the tester often uses only the alcohol meter to measure Its ethanol content. Since the density of ethanol (0.789-0.791 g/ml) and the density of methanol (0.791-0.793 g/ml) are very similar, the methanol content is often regarded as the ethanol content. From the physical properties of ethanol and methanol, it was found that their refractive index has a significant difference. The ATAGO ethanol concentration meter is a good method for quickly identifying ethanol by refractive index.
The Ethanol Refractometer (Liquor Series) is the most intuitive instrument for measuring the concentration of ethanol in aqueous solution. It can quickly determine the percentage concentration of alcohol-containing (ethanol) solution. The wine series can simultaneously measure the sugar content of the original grape juice and the alcohol content of the wine made from the original grape juice. It can also measure the sugar content of the grape juice to better control the ripening period of the grape.
Alcohol concentration meter, also known as alcohol meter, ethanol concentration meter, alcohol tester, etc., is a precision optical instrument designed to measure the ratio of alcohol concentration in aqueous solutions such as liquor and industrial alcohol. Easy to use and competitively priced. The concentration of the solution can be read by simply dropping a few drops of liquid onto the prism and then looking at the light. If T(ATC) is marked, the temperature automatic compensation system is added. PET-109 is the most versatile alcohol meter in the industry. The range of alcohol measurement is 0~45%.
The instrument is simple in structure, simple in use, less in measuring liquid, accurate in accuracy, durable in operation, accurate in measuring speed, constant temperature control, and directly displays the alcohol concentration at 20 ° C in liquid. It is a must for scientific research, food industry production and the acquisition and operation of alcohol. Ready.
