Detect equipment abnormalities faster and more accurately
with Ono Sokki’s latest Portable Vibration Meter VW-3100 — an all-in-one solution that combines advanced vibration sensing, listening, and judgment capabilities in a compact handheld form.
Handheld Vibration Meter for On-Site Vibration Diagnostics
Engineered for on-site diagnostics and predictive maintenance, the VW-3100 empowers engineers to identify imbalance, misalignment, and bearing wear with precision — without relying on large test benches or external analyzers.
Equipped with a built-in accelerometer, 24-bit A/D converter, and real-time 3-axis measurement, it captures subtle vibration changes that indicate early signs of mechanical failure.
The integrated listening function with variable band-pass filters allows users to hear the vibration spectrum directly through headphones, supporting skill transfer and intuitive troubleshooting.
With simultaneous data recording (ORF/WAV formats) and optional ISO-based evaluation features, engineers can analyze vibration data on-site or later through Ono Sokki’s O-Solution software, streamlining the workflow from inspection to analysis.
What Is a Handheld Vibration Meter?
A handheld vibration meter is a portable diagnostic instrument used for on-site vibration measurement and condition monitoring of rotating machinery such as motors, pumps, and bearings. Unlike benchtop analyzers, handheld vibration meters enable fast inspection and immediate judgment in the field.
Built for On-Site Reliability
The VW-3100 lets engineers “see” and “hear” vibration issues directly at the source. Its intuitive interface and multi-band measurement functions make it ideal for quick diagnostics, condition monitoring, and production line testing.
From identifying abnormal noise in motors to verifying product quality before shipment, this portable system brings laboratory-level accuracy into the field.
Handheld Vibration Meter vs Portable FFT Analyzer
When selecting vibration measurement tools for maintenance and diagnostics, engineers often compare a handheld vibration meter with a portable FFT analyzer.
While both are used for vibration evaluation, their purpose, complexity, and ideal use cases differ significantly.
Understanding these differences helps determine which solution best fits on-site inspection, condition monitoring, or detailed vibration analysis workflows.
