The Glass Triple Scale Hydrometer is an essential tool for any homebrewer who wants to measure fermentation accuracy and calculate alcohol content with confidence. Designed for precision and reliability, this glass hydrometer measures three critical brewing scales—Specific Gravity, Potential Alcohol, and Brix—to help you track fermentation progress and ensure consistent results in every batch of beer, wine, mead, or cider.

Made from high-quality glass, this hydrometer allows you to take accurate readings of sugar content before and after fermentation. By comparing your Original Gravity (OG) and Final Gravity (FG) readings, you can determine the alcohol by volume (ABV) of your finished brew. The clear, easy-to-read markings make this tool simple to use for beginners while providing professional-level precision for advanced brewers.

This triple scale hydrometer measures:

Specific Gravity: 0.998 – 1.160
Potential Alcohol: 0% – 21%
Brix (sugar by weight): 0 – 35%

With these three scales, brewers can monitor yeast activity, predict final alcohol levels, and adjust recipes to achieve the desired taste and body. Whether you’re brewing a strong IPA, a dry wine, or a sweet mead, this hydrometer ensures your fermentation stays on track.

The Glass Triple Scale Hydrometer includes a protective plastic storage tube and detailed instructions for use. The tube helps prevent damage when not in use and doubles as a convenient testing vessel for quick gravity checks. For best results, we recommend pairing this hydrometer with a dedicated hydrometer testing jar or test cylinder to ensure accurate readings and minimize sample waste.
