A Baumé hydrometer (commonly spelled Baume or Bume) supplied by IBEX SCIENCES is a glass laboratory instrument used to measure the density or specific gravity of liquids. It uses the Baumé (°Bé) scale, which is especially popular in industrial chemistry, food production, and manufacturing. [1, 2, 3]
Key Specifications & Features
- Material: Made of high-quality, transparent glass with a weighted bulb at the bottom to float upright. [1, 2]
- Scale Types:
- Heavy Scale: For liquids denser than water (like syrups, acids, and brines).
- Light Scale: For liquids less dense than water (like oils and alcohols).
- Common Ranges: Available in various graduation spans, such as 0–70 °Bé, 10–20 °Bé, or specific gravity ranges like 1.100–1.200 depending on your application. [, 2]
- Standard Length: Typically 250mm to 300mm for easy and precise visual reading. [1]
Common Industrial Uses
- Chemicals & Acid Testing: Measuring the strength of battery acids, sulfuric acid, and other chemical solutions.
- Food & Beverage: Checking the sugar concentration in syrups, honey, jams, and juices.
- Textiles & Tanning: Monitoring the concentration of dyes and tanning baths. [1, 2]
How to Use a Baumé Hydrometer
- Prepare the Liquid: Pour your liquid sample slowly into a tall, narrow glass graduated cylinder to avoid forming bubbles.
- Insert Gently: Lower the hydrometer carefully into the liquid until it floats freely on its own.
- Spin Softly: Give the hydrometer a quick, gentle spin. This prevents it from clinging to the cylinder walls, which can ruin the reading.
- Take the Reading: Look straight across at the liquid’s surface line against the inner scale markings to note your Baumé degree. [1, 2, 3]
