One of the coolest innovations I've seen in years is the Tilt™ - Wireless Hydrometer and Thermometer at NorthernBrewer.com.
The Tilt Wireless Hydrometer and Thermometer is at the cutting edge of new digital devices made specifically for the homebrewing community. This free-floating gadget acts as both a real-time gravity testing hydrometer and thermometer from inside your fermenter during fermentation.
Being able to check your fermentation status from your compatible Apple iPhone/iPad, Android smartphone/tablet, Tilt Pi and most Bluetooth 4.0+ Bluetooth devices means virtually no susceptibility to contamination or oxygen pickup in your fermenter. Data can be saved automatically to the cloud with free Google Sheets template or your own, favorite 3rd party cloud platform.
Tilt comes calibrated and fully-assembled with a pre-installed battery. Download the free app, sanitize the unit, drop into the fermenter and start tracking your readings with your synced device.
Multiple Unit Users: If using more than one Tilt Hydrometer and Thermometer at a time, you must use a different color Tilt for each batch. Apps will not read multiple hydrometers of the same color. Northern Brewer offers 8 different colors for multiple, simultaneous fermentations.
As more and more sugar gets converted to ethanol (which is less dense than water), the hydrometer sinks further and further into the fluid. Water has a specific gravity of 1.0. Beers usually have a final gravity of between 1.005 and 1.015 (although there are many that finish higher). The higher that the beer's finishing gravity, the more sugars are left in the beer and the sweeter it will taste. Beers that finish around 1.005 will be perceived as being "dry" because they have very little residual sugars left. This is just one tool you can use. Use it to find problems in mashing, boiling, and fermentation.
Pour your sample into a clear cylinder that is dry or has been well rinsed with your sample
Calibrate by measuring distilled water at the calibration temperature (usually 60° or 68°F) and apply the correction factor to all readings. When reading specific gravities at temperatures other than the calibration temperature, such as a post-boil gravity at 120°F, use the chart below:
