Achieve perfect beer brewing and wine making results with DURAC Triple Scale Beer and Wine Hydrometers. Includes three scales, Specific Gravity, Potential Alcohol by Volume (PAV), and Brix, that provide invaluable data points when crafting beer, wine, kombucha, mead, cider, and more in either a commercial or home brew setting.
Determine if starting mash or wort is acceptable quality to achieve desired results
Monitor fermentation process to see if variables should be altered
Determine when fermentation is complete
Calculate approximate alcohol content of the finished product
Manufactured in strict accordance with NIST as outlined in NBS Circular 555 Military STD-45662A and ISO 17025 where applicable.
