Top-Class Certified Reference Materials for Density

Density measurement market leader Anton Paar has launched production of certified reference materials. The new density standards come with the lowest possible uncertainty and are ISO 17034-certified - a unique combination on the market. They ensure supreme density measurements - no matter the instrument manufacturer.

Anton Paar, maker of the world’s most accurate digital density meter, has set up an independent, ISO 17034-accredited production site for reference materials. Anton Paar will initially offer density standards in the range from 0.75 kg/m3 to 1.25 kg/m³, specified with an uncertainty down to 0.015 kg/m³. Safety and intuitive handling are key: All materials are non-toxic and easy to fill and measure. As the typical plastic closures of other density standards are prone to exchange with ambience, Anton Paar relies on sealed safety-glass caps, so composition variation and quality loss are excluded. The ampoule cap has a shatterproof breaking point and is openable at a simple finger-press click.

ISO 17034 requirements always include those of ISO 17025: The new certified reference materials conform with both ISO standards. An ISO 17034 certificate guarantees the correctness of reference values throughout the density standard’s lifetime – not just on the day of production. The standards are available in the Anton Paar webshop.
