ROMER Absolute Arm with Integrated Scanner

ROMER Absolute Arm with Integrated Scanner

Built-in 3D Measurement Versatility

The ROMER Absolute Arm SI is an all-purpose metrology system designed to meet the needs of almost any measurement application. The fully-certified and integrated RS4 laser scanner is designed to capture 3D point data from a wide variety of surface types. It requires no calibrations, warm-up time or additional cables and controllers. It is totally integrated.

Switching seamlessly between tactile probe measurements and laser scanning at any time, the ROMER Absolute Arm SI is ideally suited to point-cloud inspection, product benchmarking, reverse engineering, rapid prototyping, virtual assembly and CNC milling.

The accuracy of the complete scanning system is fully verifiable and traceable, ensuring users always have complete confidence in the exactness of their measurements.
