Data logging vibration meter that captures both velocity and acceleration readings from rotating machinery such as motors, pumps, fans and bearings, helping catch developing faults before they cause downtime. It logs automatically to an SD card at user-selectable intervals and exports straight to Excel with no extra software, and offers RMS, peak-hold, data-hold and max/min readings on a backlit dual LCD. This unit ships with a NIST-traceable calibration certificate including full data and measurement uncertainties.
