VEE GEE 6604DS-04 is a compact dual-scale borosilicate glass hydrometer reading both Specific Gravity (0.70 to 1.00) and Baumé Light (10° to 70°) simultaneously on the same 165 mm stem. It covers light liquids — petroleum distillates, solvents, and alcohols — with coarser 0.01 SG / 1° Baumé graduations suited for quick process screening in a short-form format. Calibrated at 15°C (60°F). Autoclavable. Made in USA.
Features & Benefits
- Dual Scale — SG and Baumé Light on One Stem: Read specific gravity and Baumé Light simultaneously. At SG 1.000, Baumé Light = 10°; at SG 0.70, Baumé Light = 70°. Uses the Baumé Light formula (°Bé = 140/SG − 130) for liquids less dense than water.
- 165 mm Compact Format: Short-form instrument for use in smaller cylinders, graduated cylinders, or field applications where a full 305 mm hydrometer is impractical.
- Subdivisions: 0.01 SG / 1° Baumé: Coarser than the 6603DS-13 (0.005 SG), appropriate for screening and process monitoring where ±0.01 SG resolution is sufficient.
- Calibrated at 15°C (60°F): Standard reference temperature for density and specific gravity measurement.
- Borosilicate Glass — Autoclavable: Chemically resistant to solvents and petroleum products; autoclavable at 121°C.
- Made in USA — 1-Year Warranty.

Frequently Asked Questions
How does the 6604DS-04 compare to the 6603DS-13 for light-liquid Baumé measurements?
Both use the Baumé Light scale (°Bé = 140/SG − 130) for SG < 1.000. The 6603DS-13 (305 mm, SG 0.600–1.000, 0.005 SG subdivisions) provides finer 0.005 SG resolution across a wider range and is better for precision lab measurements. The 6604DS-04 (165 mm, SG 0.70–1.00, 0.01 SG subdivisions) is the compact short-form option with coarser resolution — appropriate for process screening or where space is limited. For petroleum products with SG below 0.70, the 6603DS-13 is required.
