DatasheetWe’ve incorporated over five decades of experience developing market-leading benchtop density meters into our new generation of density meters. With best-in-class U-tube technology based on our patented Pulsed Excitation Method, our Next-Level Density Meters are the fastest, most intelligent benchtop density meters we’ve made to date.
20-second (4-digit) results give you high throughput. Compliance with a range of standards gives you peace of mind. There’s storage space for up to 10,000 measurements. And up to 6-digit accuracy gives you results you can rely on.
Now that’s taking it to the next level.
Key features
Fast and accurate benchtop density meters
- Get market-leading precision, repeatability, and reproducibility with our patented Pulsed Excitation Method
- Maximize throughput with an ultra-fast measurement mode
- Define limits for different samples and make pass/fail QC decisions right away
- 200+ pre-installed conversion tables show concentration values immediately
- Achieve excellent results for highly viscous samples with the best viscosity correction on the market
- Get reliable measurement results for high- and low-density samples as well as inhomogeneous, sedimenting, or particle-containing ones
High-tech features simplify your lab
- Know your samples are filled correctly with FillingCheck™, which even detects microbubbles, and U-ViewTM, which shows a zoomable image of the measuring cell
- Benefit from an automatic compensation of the U-tube’s aging effects and minimized drift over the lifetime of the instrument
- Use 30+ guided user workflows and five industry-specific profiles with predefined quantities and scales
- Streamline your data management with AP Connect
Guaranteed compliance gives you peace of mind
- Comply with ASTM D4052, D5002, D1250, ISO 12185 petroleum standards, and all relevant pharmacopeias
- Satisfy all major data integrity and traceability standards (e.g., 21 CFR Part 11)
- Ensure your results are traceable to the International System of Units (SI) with ISO 17025 calibration from our accredited lab
- Use our ISO 17034-certified reference material for density to ensure your instrument is perfectly calibrated
Modularity lets you conduct multiparameter analysis
- Connect your benchtop density meter to a range of Anton Paar measuring modules to forge a multiparameter system
- Measure all relevant QC parameters from the same sample under the same conditions
- Measure more than eight parameters at once
Automated processes for higher throughput
- Automate your filling, measuring, and cleaning process by choosing from seven different sample changers (optional)
- Ensure accurate results without operator influence
- Reduce contact with dangerous substances during filling with automated sample changers
