Anton Paar launches new density meter series
30 Jul 2025
Anton Paar has launched a new generation of digital density meters that range from the three-digit DMA 502 benchtop units, to the highly accurate density meter, DMA 6002, with six-digit repeatability. These instruments have benefitted from major in-house investments in production and calibration processes at Anton Paar’s Technology Center in Graz, Austria.
U-Tube: advanced density measuring cell
The core of each density meter is the oscillating U-tube, which is now manufactured 100 % in-house to ensure maximum control over quality and performance. This has enabled significant improvements in production tolerances, consistency, and integration into a wider range of product lines – resulting in more precise, robust, and repeatable density measurements.
In parallel, Anton Paar has implemented its hydrostatic balance as a basis for production of ISO-17034 certified reference material. Together with in-house ISO 17025-certified density calibration, this forms the foundation for the highest-precision instrument calibration available.
U-Dry: effortless drying with a single swipe
Users can initiate the drying process of the measuring cell with one swipe, enabling faster, more efficient cleaning cycles. The air pump is activated automatically with just a single hand movement, and the innovative syringe illumination highlights filling errors even before the sample enters the U-tube.
U-Pulse: enhanced density measuring principle
The patented Anton Paar Pulsed Excitation Method leads to unmatched measurement result precision. Equipped with a built-in reference oscillator, the sensor allows drift-free measurements independent from any change of the measuring temperature.
U-View and FillingCheck: smart sample filling
Enhanced with a zoomable camera image, U-View allows detailed sample monitoring and immediate correction before even starting the measurement. The FillingCheck feature automatically detects microbubbles and alerts the user in case of filling errors. All incidents are documented in the results database.
