• Instantly Measure Gravity: Quickly read the gravity of unfermented wort or fruit juice in Brix and gravity. Only a few drops are needed for a sample, unlike a hydrometer! • Wide Measuring Range: Measures from 0 - 32 Brix (±0.2 Brix accuracy) and 1.000 to 1.120 SG. • Automatic Temperature Compensation: Works for temperatures between 50 - 86°F, no need to consult temperature correction charts. To use, simply apply 2 - 3 drops to the prism face, close the cover, and look through the eyepiece while aiming at a light source. Note: Not for use after fermentation starts as light refracts differently through alcohol. Check out BYO's great article here.


This Brix Refractometer is perfect for homebrewers and juice makers. You can use it during the early stages of brewing beer or making fresh fruit juice to measure the sugar content. It has a wide measuring range of 0 - 32 Brix and 1.000 to 1.120 SG with an accuracy of ±0.2 Brix. The automatic temperature compensation works for temperatures between 50 - 86°F, making it easy to get accurate readings without complex calculations.
