Understanding Baumé Scale for Winemaking
The Baumé scale is widely used in winemaking to measure sugar content in must and juice. One degree Baumé (°Baumé) is approximately equal to 1.8% Brix and corresponds to approximately 1% alcohol when the wine is fully fermented. This makes the HI96812 an essential tool for predicting potential alcohol content and monitoring fermentation progress.
Ideal Applications
Perfect for sugar analysis in wine production, grape must evaluation, juice processing, and fermentation monitoring. Essential for harvest timing decisions, quality control, and ensuring consistent wine production.

How Refractive Index Technology Works
The HI96812 measures sugar content by analyzing how light refracts through your sample. Using a yellow LED light source, precision prism, and linear image sensor, the instrument determines the refractive index and converts it to degrees Baumé according to AOAC International Official Methods of Analysis standards. The built-in temperature sensor ensures all readings are automatically compensated for temperature variations, delivering consistent, reliable results in both field and laboratory conditions.
