Achieve unparalleled precision in your liquid density testing with the Heathrow Scientific ASTM Specific Gravity Hydrometers (6700 Series). Explicitly manufactured to meet the rigorous specifications laid out by the American Society for Testing and Materials (ASTM), these laboratory-grade glass instruments provide highly accurate specific gravity measurements across a wide variety of industrial and scientific applications.
To ensure perfectly reproducible results, every hydrometer in this series is standardized and calibrated for use at a reference temperature of 15°C (60°F). The 6700 Series is divided into two distinct lengths and resolution scales: the 13-inch models offer ultra-fine 0.0005 subdivisions for maximum accuracy, while the 10.2-inch models feature 0.001 subdivisions for standard laboratory testing. Simply select the specific ASTM number or specific gravity range that corresponds to your required fluid analysis parameters.
Features & Benefits
- ASTM Compliant: Precisely manufactured to meet strict American Society for Testing and Materials standards for specific gravity instrumentation.
- Standardized Calibration: Pre-calibrated for liquid measurement at the industry-standard 15°C / 60°F.
- High-Clarity Glass: Crafted from premium clear glass to prevent sample clouding and ensure the internal scale remains highly readable.
- Multiple Resolutions: Choose between ultra-fine (0.0005) or standard (0.001) subdivisions based on your exact tolerance requirements.
*Note: These hydrometers are constructed from glass and are not recommended for use with hydrofluoric acid or highly corrosive glass-etching compounds.
