Thousands of food and beverage professionals and hobbyists have moved from less accurate and less precise optical refractometers to digital Brix measurement. Milwaukee's MA871 is the ideal tool for winemakers, brewers, fruit and vegetable growers, maple syrup producers, and food producers.
The MA871 is fast and easy-to-use with a response time under 2 seconds. Maintenance is a breeze with an easy-to-clean sealed flint glass prism and stainless steel well. The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (internationally recognized body for sugar analysis).
The Milwaukee digital BRIX refractometer is temperature compensated with a 0 to 85 percent BRIX range and ±0.2 percent accuracy. It is easy to use with simple two button operation and fast with a response time under 2 seconds. Maintenance is a breeze also with an easy-to-clean sealed flint glass prism and stainless steel well.
