A refractometer is used to measure the density of a solution, in our case how much malt sugar is in solution. Our refractometer is hand held with a metal body, flexible eye piece and rubber grip. It features a 0 to 40% Brix scale. A refractometer allows you take instant gravity readings, with just one drop, at any point during the boil, or even during the run off of the sparge during an all-grain brew. These 'during the process' readings allow you to add more water or boil longer so you can attain exactly the gravity you desire. 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.
