The Fluke 805 FC Vibration Meter is the most reliable vibration screening device available for frontline mechanical troubleshooting teams. It provides repeatable, severity-scaled readings of overall vibration and bearing condition, enabling maintenance professionals to make confident go/no-go decisions. The meter is designed for use on a wide range of machinery including fans, pumps, compressors, gearboxes, and machine tools .

A key innovation of the 805 FC is its proprietary Crest Factor+ (CF+) technology. Traditional Crest Factor (peak/RMS) does not increase linearly as a bearing degrades and can actually decrease near catastrophic failure. CF+ overcomes this limitation, providing values from 1 to 16 that increase as bearing condition worsens. For simplicity, this is translated into a four-level severity scale: Good, Satisfactory, Unsatisfactory, or Unacceptable . The meter measures vibration across two frequency bands: low (10-1000 Hz) for overall vibration and high (4000-20,000 Hz) specifically for bearing condition .

The 805 FC can store up to 3,500 measurements in the field. Data can be exported via USB to a PC, where trending analysis can be performed using included Microsoft Excel templates. This allows users to visualize patterns of deteriorating machine health over time. The meter is also compatible with the Fluke Connect mobile app, enabling wireless sharing of measurements with the entire maintenance team via ShareLive video calls. Its rugged design and intuitive operation make it an essential tool for any predictive maintenance program .
