This premium Italian glass triple scale hydrometer is built for home wine, beer, mead, and cider makers. The shorter 8" length fits perfectly in our 100cc Italian testing cylinder and uses less sample. It clearly shows Specific Gravity from 0.99–1.16, Potential Alcohol from 0–20%, and Brix/Balling from 0–35. Use it to measure your starting gravity, follow fermentation progress, and confirm when your batch is finished. Made from lead- and mercury-free glass for peace of mind. To promote a positive and satisfying customer experience, this product is covered by North Mountain Supply's 30 day hassle-free replacement program, in the event the product is damaged or defective.
