Description

Thousands of food and beverage professionals and hobbyists — from chefs and food quality professionals to brewers, winemakers, and maple syrup producers — have moved to digital Brix measurement from less accurate optical refractometers.

WHAT PEOPLE ARE SAYING

"Anyone who brews beer should find this product one of the best investments they make on any equipment."

"I am in love with this instrument. No more large samples. No more phony readings from badly made refractometers."

"Dramatically improved my commercial brewing consistency & efficiency. I can quickly stop my sparge when I get to my OG."

"I used this for finishing Maple Syrup. The refractometer was much easier than temperature and hydrometer methods."

Frequently Asked Questions

Q: What is Brix and what does the Milwaukee MA871 measure?
A: Brix (°Bx) measures the sugar content of a solution as a percentage by weight. The MA871 measures Brix from 0 to 85% — covering everything from dilute fruit juices and wort to concentrated syrups and honey. It's used by brewers to measure original gravity, winemakers to track fermentation, fruit growers to assess ripeness, and maple syrup producers to verify finished syrup density.

Q: How accurate is the MA871 and does it compensate for temperature?
A: The MA871 delivers ±0.2% Brix accuracy with Automatic Temperature Compensation (ATC) from 10 to 40°C / 50 to 104°F. This ensures accurate readings even when samples are not at the standard 20°C reference temperature — critical for field use and production environments where sample temperature varies.

Q: How much sample does the MA871 require and how fast does it measure?
A: The MA871 requires only 2–3 drops (100 μL minimum) of sample and delivers results in approximately 1.5 seconds. This makes it ideal for applications where sample volume is limited or rapid sequential measurements are needed, such as monitoring fermentation progress or checking fruit ripeness across multiple samples.

Q: How do I calibrate and clean the Milwaukee MA871?
A: Calibrate using distilled or deionized water (0% Brix reference) with simple one-point calibration. Clean the stainless steel sample well and sealed flint glass prism with a damp cloth or rinse with distilled water after each use. The IP65 rating means the unit can handle splashes and rinse water without damage.
