Still Spirits Alcometer
This alcometer is a professional grade hydrometer that has a 0% - 100% abv scale. It is used to calculate alcohol percentage in higher alcoholic beverages as it is not accurate for lower alcohol products like beer or wine. Similar in use to a brewing hydrometer, but assumes no sugar is in the solution. You must float in a sample to obtain a reading. Also called a alcoholometer.
Note: This DOES NOT work for taking readings for beer or wine. If your intent is to measure the gravity (sugar density) in beer and wine, you need a hydrometer.
