Description

Standards

Anton Paar’s long standing experience as a measuring specialist for the beverage industry (soft drinks, beer, spirits, etc.) and the highly precise results DMA delivers in next to no time have established it as the benchmark for this field.

DMA meets the strict regulations in the pharmaceutical and cosmetic industries – with electronic signatures, various user levels and internal write protection.

A thorough, fast viscosity correction and a measuring range up to 90 °C make DMA the perfect density meter for highly viscous samples such as bitumen, heavy fuel oil, or crude oil.

Since DMA only requires a minimal amount of expensive sample for its density measurement in order to deliver highly precise results after very short measuring times, the instrument is highly valued in the flavors & fragrances industry.

DMA is renowned worldwide for its robustness. The chemical industry relies on it. Apart from this, all common density/concentration tables are stored in the instrument, and new substances are easily programmed as a table or a polynomial. The use of DMA has considerably reduced the workload in the chemical industry.

The main reasons for R&D departments to choose DMA are the great accuracy, the small sample volume requirement and the temperature scan by means of the reference oscillator: The automatic temperature change right down to one-hundredth-steps guarantees easy, time-saving work.

With density measurement results as accurate as up to ± 5 x 10-6 g/cm3, a temperature accuracy of ± 0.01 °C and a sample volume requirement of only 1 mL, DMA is the high-precision reference instrument with the least sample consumption for calibration offices.

Bioethanol producers use DMA because its unprecedented accuracy assures considerable savings. The biodiesel industry chooses the instrument for its robustness and thorough, fast viscosity correction.
