Generation M Density Meter, DMA 4500 M

Product Announcement from Anton Paar

The DMA 4500 M density meter provides unparalleled ease of use and complete transparency and traceability of the sample filling and measurement process. DMA 4500 M combines state-of-the-art measuring technology with robust design and convenient handling. It is designed for years of successful laboratory work. Among the meter's numerous applications are its use in industrial quality control, in research, at authorities and at standards organizations.

Be sure of your results

  • Fast, reliable measurement results
  • Only 1 mL of sample required
  • Different user functions applicable: tables, polynomials and formulas


  • You are warned of filling errors and gas bubbles in the sample
  • Filling warnings are recorded fully automatically


  • Displays live images of the oscillating U-tube sensor and the entire filled-in sample
  • Relevant images with the sample fully and clearly visible are stored in the data memory
  • Later review of these images guarantees completely transparent measurement processes
  • Particularly when using automatic sampling systems, U-View™ and FillingCheck™ supervise the entire measurement sequence and allow later verification of the results


  • Eliminates all measurement drifts caused by temperature stress due to temperature changes or sample temperatures greatly different from the measuring temperature
  • Allows accurate and convenient density measurements in a wide temperature range
  • Only one adjustment at one temperature required
  • Patented reference oscillator (AT399051)

Automatic viscosity correction

  • Across the samples' entire viscosity range
  • Eliminates viscosity-related errors
  • No viscosity standards required

Full QM compliance

  • GMP/GLP and 21 CFR Part 11 compatibility
  • Audit Trail
  • Password protection with three user levels
  • Forgery-proof data export

Continuously updated display

  • Permanent display of the density and the viscosity-corrected density as well as all calculated properties
