The LW Scientific BRIX refractometer measures the sugar content in liquids, such as wine, beer, fruit juices, soft drinks, milk, infant formula, and yeast cultures. It can be used in the laboratory or in the field, simply by placing a few drops of liquid on the prism and reading the scale under natural light. The BRIX refractometer features a scale of 0-32%, a focusing lens, automatic temperature compensation, and comes in a hard carrying case.
