Description
The Milwaukee MA871 is a professional digital refractometer MA871 DIGITAL REFRACTOMETERS designed to measure the sugar content of fruit, energy drinks, puddings, soy milk, juices, jam, marmalade, honey, soups, jelly, tofu, and condiments.
It uses the Brix scale (0 to 85%), which measures the percentage by weight of sucrose in a water solution. Unlike manual optical refractometers, the MA871 eliminates the uncertainty of reading a manual scale by providing a precise digital readout .
