From the inventor of digital density measurement: DMA Generation M: 'Be sure' with New Anton Paar Density Meters

In 2007, Anton Paar celebrated the 40th anniversary of introducing the world’s first digital density meter utilizing its oscillating U-tube principle. Just one year later, Anton Paar launches the latest generation of laboratory density meters: Generation M.

Anton Paar DMA density meters always were the benchmark. Now Anton Paar is again expanding the limits of digital density measurement, with Generation M density meters providing a new level of user confidence and previously unattainable comfort. This new density meter generation provides unparalleled ease of use and complete transparency and traceability of the sample filling and measurement process.

These new features allow complete confidence in the sample filling and measurement process being correctly performed and therefore complete confidence in the outstanding quality of the measurement results:

FillingCheck^TM (patent application filed) automatically detects filling errors or gas bubbles in the filled-in sample. It alerts the operator of potential measurement deviations and documents the incident.

U-View^TM  displays live images of the oscillating U-tube sensor and the entire filled-in sample. Potential problems with the sample can be reliably identified in real-time or at a later review of the images automatically stored in the memory. This makes Generation M instruments the first density meters to allow later verification of the results particularly when using automatic sampling systems. Operators can safely walk away and let the instrument do the work.

ThermoBalance^TM eliminates the need for multi-temperature calibrations and allows fast and accurate measurements in the entire temperature range over extended periods of time. It eliminates drifts caused by temperature stress, such as when filling samples at temperatures greatly different from the measuring temperature and makes Generation M density meters the only instruments to fully provide these capabilities.

What else is new with Generation M?

Apart from providing automatic sample viscosity correction and high-precision platinum thermometers for temperature control, as in the previous generation, Generation M automatically determines the local air pressure, making air adjustments exact whatever the location.

The user interface has a new design: A large, easy-to-read color display with touchscreen function simplifies routine operations. For harsh environments, additional function keys are provided so that the display does not need to be touched and stays clean. A keyboard, mouse and bar code reader can be connected for convenient operation. Four USB, two RS232 interfaces and an Ethernet interface allow universal data transfer as well as secure operation for GMP, GLP and 21 CFR Part 11 applications. PC monitors of any size can be connected so that the measuring results are legible even over large distances. Space-saving plug-in sample changers manage sample viscosities of up to 35,000 mPa.s.

The available models DMA 4100 M, DMA 4500 M and DMA 5000 M provide accuracies of 0.0001 g/cm³, 0.00005 g/cm³ and 0.000005 g/cm³. Their applications include the measurement of petroleum, petroleum products and alternative fuels, the analysis of chemicals, pharmaceutical and cosmetic products, perfumes and flavors, beverages and spirits, and applications in research and development as well as in national and international calibration authorities and testing agencies.
