Facility expansion strengthens density measurement standards

Anton Paar expands DMA production and calibration capabilities at Technology Centre Graz

Anton Paar has significantly enhanced the production and calibration process of its DMA series digital density meters with major in-house investments at its Technology Centre in Graz, Austria. These developments underline Anton Paar’s commitment to providing the most accurate and reliable density measurement technology on the market.

At the core of the DMA series is a borosilicate glass U-tube sensor based on Anton Paar’s patented Pulsed Excitation Method (PEM). This sensor design is key to the high precision and sensitivity of Anton Paar density meters. Anton Paar manufactures the glass sensors entirely in-house. This strategic decision ensures maximum control over quality and performance. It also enables tighter production tolerances, easier integration into other density product lines, and improvements in both performance and cost efficiency.

In parallel, Anton Paar has further enhanced its calibration capabilities by upgrading its hydrostatic balance system. Combined with ISO 17034 and ISO 17025 certification, the upgrade ensures that DMA series calibration standards meet the highest requirements for quality, reliability, stability, and traceability – and are suitable for use as reference systems worldwide.

Additional developments include investment in a new automatic filling system, which has further minimised measurement uncertainty caused by atmospheric influences during the filling process.

Together, these developments confirm Anton Paar’s position as a globally recognised reference in digital density measurement.

All of the enhancements are the result of decades of expertise and ongoing innovation efforts from Anton Paar’s R&D team. The integration of advanced production and calibration technologies at the Graz headquarters reinforces the long-standing promise to customers worldwide: delivering superior digital density measurement with absolute confidence.
