Newly-released ROMER Absolute Arm is the most accurate ever

Hexagon Manufacturing Intelligence reveals significant upgrade to its portable measuring arm range  

Global metrology and manufacturing technology company Hexagon Manufacturing Intelligence has unveiled a new top-of-the-range addition to the ROMER Absolute Arm portable coordinate measuring machine (CMM) range.


Intended to provide absolute accuracy in high-end 3D measurement applications, the new 77 Series arm offers around 20% better scanning accuracy and 15% better touch-probe measurement accuracy than the existing 75 Series of ROMER Absolute Arm.

Available in five sizes from 2.5 m to 4.5 m measuring volumes, the 77 Series features all the proven technology of the ROMER Absolute Arm range enhanced to offer best possible accuracy while retaining the arm’s user- friendly nature. The ROMER Absolute Arm can be switched on and used immediately with no warm-up or referencing required, while probe changes can be made without recalibration to maximise flexibility on the job. Acoustic and haptic operator feedback support use in harsh shop-floor environments, while the 3000 N magnetic base supplied as standard offers mounting options for all kinds of applications.

“The 77 Series takes the accuracy performance of the ROMER Absolute Arm to a new level,” said Stephan Amann, Business Director for Portable Measuring Arms at Hexagon Manufacturing Intelligence. “Alongside the 73 and 75 Series arms, the 77 Series gives us a three-level product range so it’s easier than ever for our customers to choose a ROMER Absolute Arm for their specific application requirements and budget.”

Like the 73 and 75 Series of ROMER Absolute Arm, 77 Series arms are compatible with all Hexagon laser scanners, including the HP-L-20.8 and HP-L-8.9 external units and the RS3 integrated scanner. All the arms are available in 6- and 7-axis configurations, with 6-axis models ideal for touch-probe measurement and the 7- axis design suited for high-speed laser scanning.

The ROMER Absolute Arm 77 Series is available to order worldwide from today via local Hexagon Manufacturing Intelligence commercial operations and dealers, with shipment commencing in March.
