EasyDens by Anton Paar - Smart Hydrometer - Bluetooth Connected Density and Gravity Meter for Alcohol, Specific Gravity, Brix, Plato and Density

Anton Paar is a leading producer of analytical testing equipment for commercial breweries. Borrowing some technology from their high-end machines, the EasyDens digital gravity/alcohol tester is designed for savvy homebrewers and small commercial breweries.  It is a precision gravity/density testing unit that can accurately read gravity with a tiny 2 ml sample at any point in the brewing process.  Alcohol % can also be tracked at any point during fermentation. The unit hooks up to your smartphone via Bluetooth and stores various fermentation "profiles" enabling you to track fermentation progress, and alcohol levels and help know when it's time to keg & drink your beer!

See the documents tab for frequently asked questions about the Easy Dens.
