The Milwaukee MA871 digital refractometer Brix is used for measuring sugar levels.

Digital Refractometer Brix Milwaukee Instruments MA871 is an optical instrument for measuring refractive index and determining % Brix sugar concentration in aqueous solutions. A few seconds after placing the sample, the refractometer measures its refractive index and converts it into % Brix concentration units. The digital refractometer Brix Milwaukee MA871 eliminates the imperfections of mechanical refractometers and is also portable and lightweight (only 420 grams) for conducting mobile measurements. The Milwaukee MA871 refractometer is equipped with automatic temperature compensation function, measures the temperature of the solution in degrees Celsius or Fahrenheit (°C or °F), and displays it simultaneously with the main measurement on a large two-line LCD display along with graphical icons.

Automatic Digital Refractometer Brix Milwaukee MA871 is used to determine % Brix sugar in aqueous solutions and fruit juices, as well as the concentration of various industrial liquids and cutting fluids (coolants). The method is simple and fast.  

The MA871 refractometer can also be used in brewing to determine the extract content in the initial wort and measure densities during the fermentation process. The user can convert the %Brix measurement to specific gravity (SG) or Plato units (commonly used in brewing).

Simple calibration is performed using deionized or distilled water. A few seconds after placing the sample, the refractometer measures its refractive index and converts it into % Brix concentration units.

Milwaukee MA871 has indications for low battery power, as well as other useful device status messages.
