A refractometer instantly reads gravity, in Brix, of unfermented wort or fruit juice by measuring the degree that light passing through the sample is bent. Unlike a hydrometer, a refractometer requires only a few drops for a sample. To use, apply two to three drops to the prism face, close cover, and look through the eyepiece while aiming your refractometer at a light source.
The Specific Gravity scale will provide a quick reading of your Original Gravity. Once fermentation has begun and alcohol is present, keep track of the Brix scale and use a Refractometer Calculator for Final Gravity correction.
This is also a great tool for all-grain brewing. Easily sample your mash runoff so you know exactly when to stop sparging (typically 2 to 3 Brix). Then easily take readings before and during the boil to make sure you hit your recipe targets.
These refractometers measure from 0 to 32 degrees Brix, with an accuracy of +/- 0.2 degrees Brix. They also include automatic temperature compensation (ATC) for temperatures between 50 to 86 degrees Fahrenheit, which eliminates the need to consult temperature correction charts.
