The Extech VB450 Vibration Meter measures vibration levels in industrial machinery. Misalignment, poor balancing, structural compromises, and other factors can cause unwanted vibration increases. VB450 features a wide 10Hz to 1500Hz frequency range and provides Displacement, Velocity, and Acceleration measurement.

The meter measures acceleration (peak) from 0.1 to 199.9 m/s², velocity (RMS) from 0.1 to 199.9 mm/s, and displacement (peak-to-peak) from 1 to 1999 μm. Resolution is 0.1 m/s², 0.1 mm/s, and 1 μm with basic accuracy of ±(5% + 1 digit).

Applications for the VB450 include motors, bearings, fans, pumps, rotating machinery, and plant maintenance. The meter features automatic data hold for convenient reading capture.
