Simultaneous PPV, VDV, Dominant Frequency & Displacement
The VM-56 advanced groundborne vibration meter sets the industry standard for comprehensive vibration analysis. This sophisticated instrument simultaneously calculates measurements in accordance with multiple international standards, including DIN 45669-1 and ISO 8041. Built with RION’s signature quality and user-centric design, the VM-56 combines professional-grade precision with remarkable ease of use.
Key capabilities include:
- Attended real-time measurements
- Long-term unattended monitoring
- Real-time web-based data streaming
- Multi-standard compliance monitoring
Whether deployed for construction monitoring, rail transit studies, or structural analysis, the VM-56 delivers reliable performance in demanding field conditions.
