Certified artefacts to ensure the volumetric precision of Laser Trackers, 3D Scanners and Portable Measuring Arms (CMMs).

Certified scale bars in carbon fibre or Invar, essential for the verification and calibration of Laser Trackers and photogrammetry systems.

Ball bars certified for volumetric precision testing and calibration of CMMs and CNC machine tools.

Artefacts (magnetic cones and spheres) designed for leapfrogging and precise relocation of Portable Measuring Arms.

High-precision reference spheres with a polished finish, used for calibrating tactile probes.

Matte anti-glare sphere kits. Essential for perfect registration in 3D scanning.

Complex calibration standards (dumbbells, steps, etc.) specifically created to validate the accuracy of industrial 3D scanners.
With thousands of possible combinations, finding the exact fixture or probe tip can be a challenge. The S4METRO team helps identify the correct reference for your machine model.
