- Ultra-fast measurement mode maximizes throughput
- Best-in-class filling control provides reliable results
- 200+ conversion tables for quicker results
We’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-View™, 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
