Coordinate-measuring arms Measuring arm Absolute Arm Compact

Absolute Arm Compact is a portable CMM of high accuracy, designed to get reliable results under constrained conditions. More convenient than traditional measuring tools and much less error-prone of human factor, it allows operators to measure and control for the shortest time.
Thanks to the technology proven on the Absolute Arm series, the Absolute Arm Compact is an ideal for measuring small to medium sized parts for various applications, including:

  • check during machining;
  • control of machined parts;
  • snap positioning;
  • comparison with CAD-models;
  • adjustment and installation of parts;
  • operational quality control;
  • digitization;
  • markup and control.
With a measurable volume of up to 1.2 meters and certified to ISO 10360-2 or B89.4.22, the Absolute Arm Compact is easy to integrate into the quality control process. Being able to work without fasteners and does not require control points, the system is quickly installed and easy to operate, being a universal measuring tool available to users of various levels.

Properties and advantages::

Probing and Scanning
Specialised for ultra-high-accuracy probing while also compatible with the entry-level HP-L-8.9 Laser Scanner, concentrated multifunctionality is what the Absolute Arm Compact is all about..

Absolute Encoders
The renowned Absolute Encoders placed in every articulated joint of the Absolute Arm Compact make it the only portable measuring arm on the market to completely eliminate encoder referencing and frustrating system warm-up times – vital for measuring in confined spaces, like inside a CNC machining centre.

Advanced Materials
Built on a foundation of high-tech carbon-fibre tube construction, the Absolute Arm Compact maintains strength and thermal stability under any environmental conditions, offering reliable accuracy whatever the environment.

Effortless Movement
Designed with lightness of movement in mind, the Absolute Arm Compact is easy to handle both during and between measurements, with its unique integrated base taking the trouble out of repositioning by requiring no fixturing or mounting.

User Feedback
In even the harshest industrial environments, communicating with the Absolute Arm Compact in a way that keeps the measurement process running at full speed and efficiency has never been more simple, through our range of visual, acoustic and haptic feedback functions.

ISO Certification
The probing accuracy of the Absolute Arm Compact is certified to ISO 10360-12 as standard, with certification to ISO 10360-2 an option for users planning to use their arm in conjunction with a full-sized CMM.

Technological Foundation
Built upon years of portable measuring arm technology, the Absolute Arm Compact is the latest in a long line of market leading articulated measuring arms, from the ROMER Arm to the ROMER Absolute Arm and now beyond.
