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 density measurement with robust design and easy handling. Among the DMA 4500 M density meter's numerous applications are its use in industrial quality control, in research, at authorities and at standards organizations.
Features

 

Technology: Anton Paar’s DMA density meters combine the groundbreaking oscillating U-tube principle, the integrated reference oscillator, highly accurate platinum thermometers and a full-range viscosity correction to provide exceptional measurement performance. The new features of DMA Generation M add an outstanding level of user confidence and comfort
 
Adaptable configurations: Use the function keys below the touchscreen, a mouse or an external keyboard if you are working in a harsh environment. Enter sample identifications through a keyboard, a bar code reader, or via other means. Connect a large PC monitor or touchscreen to read the results or operate the instrument from afar. Choose from common density units such as g/cm3, kg/m3, pound/gallon and employ “customer tables” to calculate concentrations in units such as %w/w, %m/m.
 
Be sure of your results
-          Fast, reliable measurement results of high accuracy (0.00005 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 and formulas
FillingCheck™
-          Your density meter automatically detects filling errors or bubbles in the sample, alerts you and documents the incident. You can be sure of correct sample filling, whatever the conditions.
 
U-View™
-          Check the sample filling process on screen or recall stored images of the entire filled-in sample any time later. The stored images allow you to later verify correct sample filling and measurements, particularly when using Xsample 122 or Xsample 452 automatic sampling systems. So you can safely walk away and let the instrument do the work
 
ThermoBalance™.
-          Eliminates the need for multi-temperature calibrations and allows you to quickly perform accurate measurements at very different temperatures. It compensates for drifts due to temperature stress, even when filling samples at temperatures very different from the measuring temperature, and provides stable readings over extended periods of time. Generation M density meters are the only instruments to provide you with all of these capabilities.
 
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
