Maximum Performance Portable Measurement

ROMER arms have fundamentally changed coordinate metrology by going where traditional measuring machines can’t. For workpieces that are large, difficult to move, or cannot be moved to an offline inspection station, dimensional inspection at the point of production is essential. With ROMER arms, you take the CMM to the part, instead of taking the part to the CMM. The ability to quickly measure parts wherever and whenever required allows manufacturers to ensure quality, control processes, reduce scrap and eliminate re-work.

With more than twenty years of development in portable arm technology, ROMER arms lead the industry with innovative, lightweight systems designed to make portable metrology fast, easy and affordable. Manufacturers in more than 100 industries worldwide rely on ROMER products to deliver essential inspection information quickly in circumstances where traditional measuring methods are impractical or impossible.

The ROMER Absolute Arm is the latest ROMER innovation. Drawing design inspiration from the entire Hexagon Metrology product family, and all ROMER arms that came before, the ROMER Absolute Arm is the lightest, most accurate, most flexible ROMER arm ever.

Portable metrology devices not only need to be accurate, they must be reliable in less than favorable production conditions. The technologies used to build every Absolute Arm are chosen based on the experience of thousands of units in the field that are required to perform accurately, every time. The accuracy of a portable arm is, in fact, the sum of its parts.

ROMER Absolute Arm – inspection accuracy in its most mobile form.

Absolute Encoders

A first in the world of portable measuring arms: The ROMER Absolute Arm features proprietary absolute encoders in its primary axes, so the arm always "knows" the position of its joints. The result is the first portable measuring arm which does not require any kind of homing procedure before starting measurement. When the arm is turned on, it's ready to go.

Lighter, Stiffer, More Accurate

From the aerospace grade carbon fiber tubes to the simplified dual yoke joint housings, the Absolute Arm was designed to be the lightest, yet stiffest ROMER arm we've ever built. The base 2.5 meter arm weighs just 7.5 kg, lighter than similar 2.4 meter arms. Combined with the improved accuracy from the proprietary in-house designed and built absolute encoders, it's also the most accurate ROMER arm to date.

Absolute Flexibility

The all-new ROMER Feature Pack concept unfolds the full potential of a portable measuring arm. Utilizing a common docking connector to the base of the arm, feature packs allow you to add, remove, or change features on an arm as required. As new feature packs are released, an Absolute Arm can be upgraded in the field with new capabilities.
