Alcohol Hydrometer


Use this great Proof and Tralles Alcohol Hydrometer to quickly and accurately measure alcohol percentage. Made in the U.S.A., this alcohol meter measures up to 200 proof volumes. Alcohol hydrometers are used to find the alcohol percentage of alcohol by volume (abv) in dry or distilled liquors. It does this by calculating the density of the liquid. The heavier the fluid, the higher the hydrometer floats. Alcohol has a different density than sugar water. So when spirits are made from sugar-water and alcohol, you can use a hydrometer to determine how much of the sugar has been converted into alcohol.

Pour a sample of the spirit to be tested into a tall glass or high chemical tolerant plastic cylinder, make sure to leave enough space for the alcoholmeter. For your results, read the mark where the liquid level crosses the stem of the alcohol hydrometer. Our Alcohol Hydrometers are very delicate measuring devices that are made from glass.

This Hydrometer was manufactured and calibrated in accordance with the National Institute of Standards and Technology (NIST) formerly the National Bureau of Standards (NBS) and outlined in NBS Circular 555.
