A new benchmark for petroleum and petrochemical density measurement

Anton Paar, the world market leader in density measurement, has launched a new generation of digital density meters designed for demanding quality control and R&D laboratories working in petroleum and petrochemical applications.

DMA 4002, DMA 5002, and DMA 6002 support fast, traceable density measurements across the hydrocarbon value chain – from crude oil, fuels, and lubricants to solvents, additives, and petrochemical intermediates.

With high repeatability – including world-leading six-digit repeatability for DMA 6002 – the new series helps laboratories meet standard-driven testing requirements such as ASTM D4052, ASTM D5002, ASTM D1250, and ISO 12185.

Anton Paar has invested heavily in its Technology Center in Graz, Austria, to control the critical factors behind high-precision density measurement. The oscillating U-tube measuring cell at the heart of the series is now manufactured completely in-house, ensuring maximum control over production tolerances, consistency, and performance. To support precise instrument calibration, Anton Paar’s hydrostatic balance serves as the basis for producing ISO 17034-certified reference material, which is used together with in-house ISO 17025-certified density calibration.

The new DMA series improves daily operation with features for drying, sample handling, measurement stability, and filling control. U-Dry starts drying the measuring cell with a single swipe, while syringe illumination helps identify filling errors before the sample enters the U-tube. U-Pulse technology – with a built-in reference oscillator – enables drift-free measurements independent of temperature changes. The U-View feature provides a zoomable camera image for sample monitoring, while FillingCheck automatically detects microbubbles and documents filling errors.

With advanced in-house production, precise calibration, and smart workflow features, DMA 4002, DMA 5002, and DMA 6002 give petroleum and petrochemical laboratories the accuracy, reliability, and efficiency required for demanding density measurement applications.
