This Alcoholmeter is calibrated to test ethyl-alcohol and demineralized water at 20'C. This instrument permits to know the alcohol content in a solution of water and alcohol.
The current official unit of measure in the E.C. is %Volume. That means the % of volume of ethyl alcohol contained in a solution of water and alcohol. The scale is graduated from 0% to 100% . 0% is water without alcohol.
It is used to measure alcohol content in distilled spirits/liquors not in fermented beverage.
Handle it carefully, to have a correct reading, use it in a cylinder large enough to let the Alcoholmeter float freely. Read blow meniscus.
We train both how to use and calibration. When alcohol solution tends to have raised temperature above 20'C but we can teach you how to correct the reading. Kindly call or whatsapp for details and business.
