Density Tester for Petroleum Products and Crude Oil

Density Tester for Petroleum Products and Crude Oil (ASTM D1298)

The QualiDT™-D1298 by Qualitest is a high-precision hydrometer-based density tester engineered to measure density, relative density (specific gravity), and API gravity of liquid petroleum products and crude oil in strict compliance with ASTM D1298.

Designed around the traditional hydrometer method, this system delivers dependable and consistent results with a clear glass water bath that includes integrated bottom illumination for improved reading clarity. Advanced PID auto-tuning ensures stable and accurate temperature regulation throughout testing, supporting repeatable measurement conditions.

This instrument is well suited for laboratories, refineries, fuel certification facilities, and petrochemical quality control and assurance environments where accurate petroleum density analysis is essential.

Key Applications

• Measurement of API gravity for crude oil

• Density analysis of gasoline, diesel, and lubricants

• Specific gravity evaluation for petroleum blending and certification processes

• Compliance testing in accordance with ASTM D1298 for laboratories and oil terminals
