Specific Gravity Tester DW-G
It is equipped with high precision constant temperature water bath, pycnometer, beaker and thermometer, it is suitable for the test of density and relative density of various bitumen materials.
This tester has the advantages of advanced design, high temperature control precision and good constant temperature effect. It is the ideal instrument for the bitumen production enterprises, construction units, research institutes, colleges and universities and other units to test the density and relative density of various bitumen materials.
In addition to being used as a special instrument for bitumen density and relative density test, since it is a multi-functional circulating constant temperature water bath instrument, it can not only provide a constant temperature bath for various of high and low temperature test; the circulating system of the constant temperature water bath also can be used in the other closed circulation systems, and suitable for multi-purpose use in relevant laboratories.

Fast, Accurate Specific Gravity Measurement with the Specific Gravity Tester DW-G
Ensure precise density-based quality control for liquids with the Specific Gravity Tester DW-G—a compact, digital hydrometer engineered for rapid determination of specific gravity (SG), density, and API gravity in petroleum products, chemicals, beverages, and industrial fluids. Compliant with ASTM D1250, ISO 3838, and IP 160, the DW-G delivers laboratory-grade results in seconds using the oscillating U-tube principle—eliminating the need for glass hydrometers, pycnometers, or manual calculations.
Engineered for Simplicity and High Accuracy
The DW-G Specific Gravity Tester requires just 1–2 mL of sample, which is drawn into a temperature-controlled U-shaped glass tube. The instrument measures the oscillation frequency of the filled tube to calculate specific gravity with ±0.0001 g/cm³ accuracy. Integrated Peltier temperature control maintains the sample at a precise reference temperature (typically 15°C, 20°C, or 60°F), ensuring standardized, repeatable results regardless of ambient conditions.
- High Accuracy: ±0.0001 g/cm³ – Suitable for custody transfer, formulation, and QC applications.
- Automatic Temperature Control (±0.02°C) – Built-in Peltier system eliminates external water baths.
- Multi-Parameter Output – Simultaneously displays specific gravity, density (g/cm³), and API gravity.
- Wide Measurement Range: 0.5–2.0 SG – Handles light solvents, fuels, syrups, acids, and heavy oils.
- Large LCD Display & One-Button Operation – Simple interface for quick readings in field or lab.
- Easy Cleaning & Low Sample Volume – Integrated flush port minimizes cross-contamination.
Trusted Across Industries for Density-Based Verification
Specific gravity is critical for fuel blending, alcohol content estimation, battery electrolyte testing, and raw material verification. The DW-G replaces error-prone manual methods with a fast, digital solution that supports ISO 17025, GMP, and pharmaceutical workflows. Its rugged design and portability make it ideal for use in refineries, beverage plants, chemical warehouses, and educational labs.
Whether you’re checking ethanol concentration, verifying transformer oil quality, or calibrating syrup batches, the Specific Gravity Tester DW-G delivers reliable, traceable results—in seconds.
