DMA Generation M

The DMA Generation M density meters measure the density and concentration of liquids. They provide preset measuring methods and integrated conversion tables for many applications. The FillingCheckTM function automatically detects filling errors and gas bubbles in the sample to avoid measuring errors.

Accuracy, density:
0.0001 g/cm³ (DMA 4100 M)
0.00005 g/cm³ (DMA 4500 M)
0.000005 g/cm³ (DMA 5000 M)

Repeatability s.d., density:
0.00005 g/cm³ (DMA 4100 M)
0.00001 g/cm³ (DMA 4500 M)
0.000001 g/cm³ (DMA 5000 M)

Benefits of DMA Generation M at Distillate fuel oil

DMA 4100 M and DMA 4500 M can directly measure API gravity (calculated from true density), a necessary parameter for quality control of final products. The conversion from density to API gravity is implemented according to ASTM D1250 (product group B: refined products).  A sample changer is used for high sample throughput (Xsample 452) and allows for highly repeatable results (Xsample 352/452).

DMA 500

DMA 500 is a convenient, compact laboratory density meter providing renowned DMA measurement quality at the push of a button. Operations with DMA 500 are safe against voltage fluctuations and power outages due to the instrument’s integrated rechargeable battery, which also enables flexible off-the-line operation. The U-ViewTM live camera image of the measuring cell allows for visual inspection of the filling process and is supported by an automatic FillingCheckTM resulting in a high level user-support.

Accuracy, density:
0.001 g/cm3

Repeatability s.d., density:
0.0002 g/cm3

Min. sample volume:
approx. 1 mL

Maximum off-the-line operation:
2 h (optionally 6 h)

DMA 4200 M

The DMA 4200 M density meter determines density and specific gravity at sample pressures up to 500 bar and temperatures up to 200 °C. DMA 4200 M  is the expert solution for highly viscous samples with high melting points like bitumen, asphalt or tar, for volatile samples like fuel and gases like LPG (liquefied petroleum gas).

Density range:
0 to 3 g/cm3

Temperature range:
-10 °C to 200 °C

Pressure range:
0 bar to 500 bar

Accuracy, density:
0.0001 g/cm3
