Milwaukee Refractometers

Milwaukee Digital Brix Refractometer Black, MA 871 is a sophisticated and precise instrument designed to measure the concentration of dissolved solids, particularly sugars, in liquids. This advanced version of the traditional Brix refractometer employs digital technology to provide accurate and easy-to-read measurements, making it an invaluable tool in various industries such as food and beverage production, agriculture, and scientific research.
At its core, a digital Brix refractometer operates on the principle of light refraction. When light passes through a liquid sample containing dissolved solids, its direction changes based on the refractive index of the liquid. The degree of light bending is proportional to the concentration of dissolved solids in the sample, allowing for the determination of Brix readings.
Unlike its analog counterpart, a digital Brix refractometer features an integrated electronic system that automates the measurement process. The liquid sample is placed on the prism surface, and the instrument's light source and detector work together to analyze the refracted light. The resulting data are processed by an internal microcontroller, which then displays the Brix measurement digitally on a built-in screen.
One significant advantage of a digital Brix refractometer is its precision and ease of use. The digital display eliminates the need for manual interpretation of readings, reducing the chances of human error. Furthermore, many digital models offer additional features such as automatic temperature compensation (ATC), which adjusts the measurement to account for temperature variations that could affect accuracy.
Digital Brix refractometers are especially popular in industries where precise sugar concentration measurements are crucial. In the food and beverage sector, they assist in monitoring sugar levels during the production of beverages, jams, jellies, and syrups. In agriculture, these refractometers are utilized to assess fruit ripeness and monitor the quality of juices and other plant extracts.
Some advanced digital Brix refractometers can store measurement data for future analysis and provide connectivity options for data transfer and integration with computer systems. This facilitates record-keeping, quality control, and data management in industrial applications.
In summary, a digital Brix refractometer is an advanced optical instrument that utilizes digital technology to provide accurate and easily readable measurements of dissolved solids, particularly sugars, in liquids. Its precision, automation, and additional features make it an essential tool for industries requiring precise control over product quality and processes involving liquid concentration analysis.

MA871 Digital Brix Refractometer
The MA871 is an optical instrument that employs the measurement of refractive index to determine the % Brix of sugar in aqueous solutions. The method is both simple and quick.
Samples are measured after a simple user calibration with deionized or distilled water.
Within seconds the instrument measures the refractive index of the sample and converts it to % Brix concentration units.
The MA871 digital refractometer eliminates the uncertainity associated with mechanical refractometers and is easily portable for measurements in the field.
The measurement technique and temperature compensation employ methodology recommended in the ICUMSA Methods Book (Internationally recognized body for Sugar Analysis).
Temperature (in °C or °F) is displayed simultaneously with the measurement on the large dual level display along with icons for Low Power and other helpful message codes.
Key features include:
Dual-level LCD
Automatic Temperature Compensation (ATC)
Easy setup and storage
Battery operation with Low Power indicator (BEPS)
Automatically turns off after 3 minutes of non-use.
