Precise, Fast Density Measurement with the Density Tester DDT-241
Achieve laboratory-grade density and specific gravity results in seconds with the Density Tester DDT-241—a high-precision digital density meter engineered for petroleum, chemical, pharmaceutical, and food & beverage laboratories. Utilizing the oscillating U-tube principle, the DDT-241 delivers exceptional accuracy (±0.0001 g/cm³) for liquids ranging from light solvents to viscous oils, fully compliant with ASTM D4052, ISO 12185, and IP 557 standards.
Engineered for Speed, Accuracy, and Simplicity
The DDT-241 Density Tester measures density by detecting the resonant frequency of a filled U-shaped glass tube—providing results in under 2 minutes with minimal sample volume (1–2 mL). Its integrated Peltier temperature control maintains the sample at a precise, user-selectable temperature (typically 15°C, 20°C, or 25°C), ensuring standardized, repeatable measurements 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 need for external water baths.
- Wide Measurement Range: 0–3 g/cm³ – Handles gasoline, ethanol, acids, syrups, and heavy oils.
- Calculates Multiple Parameters – Simultaneously displays density, specific gravity, API gravity, and concentration (for pre-programmed solutions).
- Large Color Touchscreen & Data Management – Stores 1,000+ results; USB export to CSV for reporting.
- Easy Cleaning & Low Sample Volume – Integrated flush port and <2 mL sample requirement reduce waste and cross-contamination.
Trusted Across Regulated Industries
From verifying fuel blending accuracy and ethanol content to ensuring syrup consistency in beverages or solvent purity in pharma, the DDT-241 replaces hydrometers and pycnometers with a fast, automated, and traceable solution. Its compliance with international standards makes it ideal for ISO 17025 labs, refineries, and quality control departments requiring auditable, high-throughput analysis.
Whether you’re certifying jet fuel or developing a new chemical formulation, the Density Tester DDT-241 delivers the precision and efficiency your workflow demands.
