Density Meter DMA 4200 M
The Anton Paar DMA 4200 M density meter is a precise and fast instrument for measuring the density of heavy petroleum samples. It complies with ASTM standards and features a low sample volume requirement, easy cleaning, and reliable performance at high temperatures and pressures.
The new DMA 4200 M is a density meter for exceptional conditions. It measures the density at temperatures between -10 °C and 200 °C and elevated pressures up to 500 bar. The Pulsed Excitation Method used by DMA 4200 M delivers the most stable density results based on comprehensive knowledge of the oscillation characteristics. The new automatic bubble detection, FillingCheck™, makes the DMA 4200 M compliant with ASTM D4052 and ASTM D5002. Viscosity influence is eliminated by a fast new viscosity correction, ensuring density results with an accuracy of up to 0.0002 g/cm3. The new Temperfect™ feature of DMA 4200 M allows immediate density measurements at any temperature between 0 °C and 150 °C at ambient pressure.
DMA 4200 M improves, accelerates, and simplifies density measurement of heavy petroleum samples.
