Moonshine hydrometers are for reading the density of a mash and are used to confirm the completion of fermentation or to calculate the alcohol content from fermentation by using readings at the start and end of fermentation. Hydrometers will not work in a distilled spirit.
This distilling hydrometer has both the Specific Gravity Scale and Potential Alcohol scale. 0.980 to 1.170 Specific Gravity reading.
30cm (12”) long laboratory grade Hydrometer.
Use the moonshine alcohol tester by taking a reading before and after fermentation. Subtract the 1st reading from the second to see your potential alcohol volume.
