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 Wax

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 D: lubricants).  A sample changer is used for high sample throughput (Xsample 452) and allows for highly repeatable results (Xsample 352/452).
