Milwaukee MA871 Digital Brix Refractometer | 0–85% | ±0.2% ATC | Brewing, Winemaking & Food Testing
Milwaukee MA871 Digital Brix Refractometer – Professional Sugar Analysis for Brewers, Winemakers & Food Producers The Milwaukee MA871 is a professional-grade digital Brix refractometer trusted by thousands of food and beverage professionals — from commercial brewers and winemakers to maple syrup producers, fruit growers, and food quality labs. With a 0–85% Brix range , ±0.2% accuracy , and automatic temperature compensation (ATC) , it delivers the precision and repeatability that optical refractometers simply cannot match.
Results in under 2 seconds. Only 2–3 drops of sample needed. One-point calibration with distilled water. IP65-rated stainless steel sample well. This is the instrument that replaces your optical refractometer and doesn't go back in the drawer.
What People Are Saying "Anyone who brews beer should find this product one of the best investments they make on any piece of 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. Now I can quickly stop my sparge when I get to my OG."
"I used this for finishing Maple Syrup. I had been trying to determine sugar content using temperature and a hydrometer. I found both very difficult to use. The refractometer was much easier."
Key Features
0–85% Brix Range: Covers the full spectrum from low-sugar beverages to high-Brix syrups, jams, and concentrates
±0.2% Brix Accuracy: Lab-grade precision for consistent, repeatable measurements in production and QC environments
1.5-Second Measurement Time: Fast results with only 2–3 drops (100 µL minimum) of sample — no waiting, no large sample volumes
Automatic Temperature Compensation (ATC): Compensates automatically between 10–40°C (50–104°F) — accurate readings regardless of sample or ambient temperature
ICUMSA-Compliant Methodology: Measurement technique follows methodology recommended in the ICUMSA Methods Book — the internationally recognized standard for sugar analysis
IP65-Rated Enclosure: Dust-tight and protected against water jets — built for real production and lab environments
Stainless Steel Sample Well with Flint Glass Prism: Easy to clean, resistant to staining and corrosion from acidic samples
Dual-Level LCD Readout: Displays both Brix and temperature simultaneously
Simple One-Point Calibration: Calibrate with distilled or deionized water — no complex multi-point calibration required
Two-Button Operation: Minimal learning curve — measure and calibrate with just two buttons
5,000-Hour Battery Life: 9V battery included; auto-shutoff after 3 minutes of non-use extends battery life further
Battery Level Indicator: Know when to replace before it affects your measurements
Ideal Applications
Craft & Commercial Brewing: Monitor original gravity (OG), track fermentation, and stop sparge at the right Brix for consistent batch-to-batch results
Winemaking: Measure grape must sugar content, track fermentation progress, and determine harvest timing
Maple Syrup Production: Accurately determine sugar content for finishing — far more reliable than temperature or hydrometer methods
Fruit & Vegetable Growing: Measure Brix as an indicator of crop ripeness, quality, and nutritional density
Food Production & QC: Verify sugar concentration in jams, jellies, sauces, juices, and concentrates
Beverage Industry: Quality control for soft drinks, juices, syrups, and other sugar-containing products
