DMA 4100/4500/5000 M Density meter

The new Generation M density meters combine the DMAs’ known excellent measuring capabilities with unparalleled levels of user confidence and comfort. A host of new features provides complete confidence in the sample filling and measurement process and therefore in the quality of the measurement results.

The DMA 5000 M is the most accurate density meter on the market and is ideal for numerous fields of application and successful continuous operation in the laboratory. First-class digital density measurement provided by the robust DMA Generation M density meters is applied in industrial quality control, in research, at authorities and standards organizations. This series of density meters provides unparalleled ease-of-use at an attractive price and ensure complete transparency and traceability of the sample filling and measurement process.

Be sure of your results

  • Fast, reliable measurement results at the highest accuracy (up to 0.000005 g/cm³)
  • Only 1 mL of sample required
  • Preset measuring methods for different applications
  • Integrated conversion tables for simple density and concentration measurement
  • Different user functions applicable: tables, polynomials, formulas, linear functions and constants


  • Detects filling errors and gas bubbles in the sample
  • Generates and records filling warnings

U-View™ (DMA 4500 M and DMA 5000 M)

  • 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
  • Different security levels and increased security settings
  • Electronic signature

Continuously updated display

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