Zero-G counterbalance makes the portable CMM feel nearly weightless during operation, improving productivity across probing and 3D scanning tasks.

Ease-of-Use

Visual, acoustic and haptic feedback helps guide operators and maintain measurement reliability in noisy or vibration-filled environments. The modular wrist and Zero-G counterbalance improve comfort during longer inspections while providing easier access to confined features. An on-wrist touchscreen allows users to control measurements and review results, alerts and notifications without repeatedly returning to the computer.

Connected

Robust, stable Wi-Fi enables cable-free measurement around components and production areas, improving mobility and reducing workspace obstruction. The Absolute Arm 7-Axis integrates with major metrology software, data-management and asset-management tools, supporting connected inspection, measurement analysis and equipment monitoring across quality-control workflows.

Range

The Absolute Arm portfolio offers Compact, 6-Axis and 7-Axis models across three accuracy levels, 83, 85 and 87, and seven sizes, creating 36 available configurations. Measurement volumes start at 1.2 metres for the Compact model, while 6-Axis and 7-Axis systems cover diameters from 2.0 to 4.5 metres. This range allows users to select the reach and accuracy required for components, large assemblies and complex industrial inspections.

Features and Benefits

Probing and scanning

The Hexagon Absolute Arm 7-Axis combines high-accuracy tactile probing with high-productivity 3D laser scanning using the Absolute Scanner AS1 or AS1-XL. This multifunctional portable CMM improves inspection efficiency by allowing operators to measure complex features and capture detailed surface data with one versatile system.

Absolute Encoders

Absolute Encoders in every articulated joint eliminate encoder referencing and system warm-up times, allowing measurements to begin immediately. This technology supports accurate, productive dimensional inspection, including measurements in confined or difficult-to-reach areas.

Advanced Frame Structure

The high-tech carbon-fibre Advanced Frame Structure combines strength, lightweight handling and thermal stability. It helps the measuring arm maintain reliable accuracy when operating in changing workshop, production and industrial conditions.

Complete Protection

As the world’s first portable measuring arm rated IP54, the Absolute Arm provides protection against dust and water ingress. Reliable operation at ambient temperatures up to 45°C supports accurate measurement in demanding manufacturing and production environments.

Effortless movement

Infinite-rotation, low-friction grips and an advanced counterbalance system make the arm light and responsive throughout its measurement volume. This ergonomic design reduces operator fatigue, supports controlled movement and helps maintain accuracy during extended probing and 3D scanning tasks.

User feedback

Visual, acoustic and haptic feedback communicates measurement and system information directly to the operator. These clear alerts support efficient, reliable inspection even in noisy, vibration-filled industrial environments.

Absolute portability

Even the largest Absolute Arm 7-Axis configuration weighs only 10.5 kilograms, making setup, movement and repositioning easier across inspection areas. Its purpose-designed, shock-resistant carrying case protects the portable coordinate measuring machine and its accessories during storage and transport.

ISO certification

Absolute Arm 7-Axis probing accuracy is certified according to ISO 10360-12 as standard. Complete scanning-system accuracy is certified according to ISO 10360-8 Annex D when the arm is supplied with an Absolute Scanner AS1, AS1-XL or RS5 Laser Scanner.

Touchscreen Wrist Display

The OLED touchscreen wrist display allows operators to control measurements and review results, alerts and system information directly from the arm. Reducing the need to return to the computer helps create a faster and more focused inspection workflow.

Essential security

HomeDock and SmartLock allow the Absolute Arm to be safely secured between measurements. These functions help protect installed probes and laser scanners from accidental damage while preserving their factory-calibrated accuracy.

Asset management

Compatibility with Hexagon Metrology Asset Manager enables users to monitor arm status, health and performance remotely in real time. This connected asset-management capability supports proactive equipment oversight and dependable quality-control operations.

Technological foundation

The Absolute Arm 7-Axis builds on decades of articulated measuring-arm development, progressing from the ROMER Arm and ROMER Absolute Arm to Hexagon’s current portable metrology platform. This proven technological foundation combines established measurement expertise with modern probing, scanning and connectivity capabilities.
