The VM120M Vibratory Stress Relief System is a professional solution for performing Vibratory Stress Relief (VSR) on welded steel structures and fabricated components. The system enables rapid identification of structural resonant frequencies while providing precise control, monitoring and complete documentation of the stress relief process.

The VM120M is designed to monitor vibration response in two independent directions, allowing the operator to detect orthogonal vibration modes and maintain full control of the process, even when complex vibration patterns occur.

Thanks to its portable design and advanced automation, the VM120M is suitable for both workshop and on-site applications across a wide range of industries.
