Density Meters DMA Generation M

Exact and fast, digital density measurement for a number of applications and successful continuous use in the lab. The unit can be used in industrial quality control, research, public authorities and standardisation organisations. Comfortable density measurement over a wide temperature range.
  • Robust design.
  • High user-friendliness.
  • Absolute transparency and traceability of sample filling- and measurement process.
  • Only 1 ml of sample required.
  • Preset measurement methods for different applications.
  • Integrated conversion tables for simple density- and concentration measurement.
  • Different customer-specific functions available: tables, polynomial and formulas.
  • FillingCheck: automatically detects filling errors and gas bubbles in the filled sample and generates a warning message.
  • ThermoBalance: eliminates the need for multi-temperature calibrations and allows to quickly perform accurate measurements at very different temperatures. It compensates for drifts due to temperature stress.
  • Patented reference oscillator (AT 399051).
  • Fast full-range viscosity correction.
  • Calibration of viscosity standards is not required.
  • Full QM suitability.
  • Complies with 21 CFR Part 11 and cGLP / GMP requirements.
  • Audit Trail.
  • Password protection with 3 user levels.
  • Forgery-proof data export.
  • Continuous density display.
  • Density and viscosity-corrected density as well as values derived from these are updated on the display continuously.

DMA 4500 M:
  • U-View™: visually inspects the measuring cell by means of a real-time camera. Pictures of the measuring cell are saved with the acc. measuring data, ready to be recalled for verification of correct sample filling any time later.
