ROMER Absolute Arm Compact

ROMER Absolute Arm Compact

Concentrated Measurement Accuracy

Combining ultra-high accuracy with a small form factor, the ROMER Absolute Arm Compact has been designed for optimum results in tight spaces.

Featuring an integrated base and a unique counter-weight balancing system for improved ease-of-use, the ROMER Absolute Arm Compact can be placed anywhere, even inside a machining centre, guaranteeing accuracy where it’s needed most.

Concentrating the advanced technology of the full-sized ROMER Absolute Arm into an even more portable package, this arm represents the perfect choice for measuring small-to-medium parts with absolute accuracy. The model is fully compatible with WiFi operation and the HP-L-8.9 laser scanner.

Certification

Full Accuracy with B89 or ISO

The ROMER Absolute Arm Compact is offered with a choice of two certifications: B89.4.22 or ISO 10360-2. Each certification quotes the arm accuracy in a different way. B89 is the standard certification typically used for portable CMMs and quotes the arm performance (volumetric accuracy and point repeatability).

ISO certification is a stationary CMM type certification that quotes the arm accuracy according to a variable ‘L’, where ‘L’ is equal to the length of measurement that is being performed. A higher L-value denotes a larger measurement distance, such that ISO-certified accuracy increases with lower L-values.
