Best of all, it only requires a few drops of liquid for an accurate reading. No need to lose a whole hydrometer test jar of beer or wine in the process.
Our refractometer comes complete with a screwdriver for calibration, a microfiber cloth for cleaning the prism surface, a pipette for sample collection, and detailed usage instructions.
Check out our Refractometer Calculator, which will allow you to convert Brix to gravity before and during fermentation.
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, only a few drops are required for a sample. To use, apply 2-3 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 the Refractometer Calculator for Final Gravity correction.
It is also a great tool for All-Grain Brewing. Easily sample your mash runoff so you know exactly when to stop sparging (typically 2-3 Brix). Then easily take readings before and during the boil to make sure you hit your recipe targets.
Our refractometers measure from 0-32° Brix, with an accuracy of +/- 0.2° Brix. They also include automatic temperature compensation for temperatures between 50-86° F, which eliminates the need to consult temperature correction charts.
