Portable Scanning and Probing for All Manufacturing Needs

By combining scanning and probing into a single device, the Hexagon Absolute Arm (formerly known as the Romer Arm) offers versatile measurements for any part, capturing data in various ways to suit different objectives.

Innovative RFID technology allows users to switch between probes and scanners effortlessly, without the need for new calibration.

Key Features & Benefits

Total movement for an arm

Zero-G Counter Balances and low friction rotating grips minimize user fatigue and maximize scanning angles.

Swap settings on the device

Change between different user profiles, capture devices, and take quick measurements all on the arm without needing to put the device down and use a computer mouse.

Absolute portability

Hot-swappable batteries and wireless connectivity allow for the device to work untethered to an outlet or computer system. Different sized arms allow for placing inside of tight spaces or on moveable tables for anywhere on the shop floor.

Hot-swap accessories

Switch between a scanner and probe with the click of a button. When you want to switch the scanner or probe accessory used, simply detach and re-attach your new device without needing to recalibrate the arm.

Frequently Asked Questions

Which Absolute Arm is right for me?

It depends on the size of the item you need to scan and what your tolerances are. The Absolute Arms come in lengths ranging from 1.2 meters to 4.5 meters and are available in three tiers based on accuracy testing: 83 for standard measurement requirements, 85 for more demanding tolerances, and 87 when the highest level of portable accuracy is needed.

Do I need to recalibrate the arm if I go from probing to scanning?

No, it’s seamless; there is no need to recalibrate when switching from probing to scanning.

Can multiple different probes be used on the same arm?

Yes, using RFID inside the devices allows for hot-swapping of probes. The Absolute Arm is compatible with a wide range of probes, scanners, and other accessories without the need to re-calibrate between swaps.

Can the device be repositioned for larger parts outside of the arm’s size?

Accessories such as Leap-Frog kits can be used to quickly reposition the device in designated environments and still maintain part tracking, reducing the need to manually align data afterwards.

What certifications does the device have?

Probing is certified under ISO10360-12 standards and scanning under ISO10360-8 Annex D. Accuracy can also be verified by users using supplied CMM artefacts.

What environmental conditions can the device run in?

Designed to be used inside of machinery like lathes and mills in order to measure right after manufacturing, the Absolute Arm has an IP54 dust/splash rating and can operate in 5 – 45 degrees Celsius.
