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.
Portable Vibration Meter for On-Site Vibration Diagnostics
Detect abnormal vibration and mechanical issues instantly — without FFT setup or complex analysis.
Designed for maintenance and inspection engineers, the VW-3100 enables quick on-site diagnosis of imbalance, misalignment, and bearing wear — so you can decide immediately whether action is required, directly at the equipment.
With built-in vibration sensing and real-time multi-axis measurement, the VW-3100 captures early signs of abnormal vibration that are often missed during visual inspection alone.
Its integrated listening function with adjustable band-pass filters lets users hear vibration characteristics directly, supporting intuitive troubleshooting and skill transfer — even without advanced vibration analysis expertise.
What Is a Portable Vibration Meter?
A portable 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, portable vibration meters enable fast inspection and immediate judgment in the field.
VW-3100 Vibration Meter
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.
Portable Vibration Meter vs Portable FFT Analyzer
When selecting vibration measurement tools for maintenance and diagnostics, engineers often compare a portable 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.
