This kit centers on a triple-scale hydrometer designed for home fermentation projects. It includes a triple-scale hydrometer, a 250 ml plastic test jar, a cleaning brush, a soft cloth, an instruction sheet, and a storage bag to keep components together for easy setup. The hydrometer reads specific gravity from 0.99 to 1.17, Brix from 0 to 35, and potential alcohol from 0 to 20 percent, with lead-free and mercury-free construction and clear, easy-to-read scales. To use, pour a sample into the jar, insert the hydrometer, and let it float freely without touching the walls, then read the color-coded scale. This kit is suitable for monitoring fermentation in beer, wine, mead, and kombucha, helping you track fermentation progress and sugar depletion with straightforward steps. The included items are selected for simple cleaning and repeated use, and the carry bag and jar provide a tidy, portable setup. While aimed at home fermentation, the kit can also support educational demonstrations or hobby projects that involve liquid density measurements and fermentation dynamics. The scales are designed for quick cross-reference, and calibration stability supports consistent results across batches. Storage bag protects components when not in use. This setup minimizes exposure to air and reduces sample handling.
