The Reliable, Repeatable, Accurate Way to Check Bearings and Overall Vibration

Make go or no-go maintenance decisions with confidence. The Fluke 805 Vibration Meter is the most reliable vibration screening device available for frontline mechanical troubleshooting teams that need repeatable, severity-scaled readings of overall vibration and bearing condition.

What Makes the 805 the Best Choice?

  • A meter – not a pen – that measures overall vibration as well as specific variables like bearing condition and temperature, to provide a more complete picture
  • A combination vibration and force sensor tip that compensates for user variance (force or angle) yielding accurate, repeatable readings
  • A four-level severity scale and onboard processor calculate bearing condition and overall vibration using easy-to-understand textual alerts (Good, Satisfactory, Unsatisfactory, Unacceptable)
  • Sensor sensitivity can read a wide range of frequencies (10 to 1,000 Hz and 4,000 to 20,000 Hz) covering most machine and component types
  • Straight-forward user interface that minimizes the user inputs to RPM range and equipment type

Other useful features:

  • Measures overall vibration (10 Hz to 1,000 Hz) for acceleration, velocity, and displacement units of measurement for a wide variety of machines
  • Provides Crest Factor+ technology for reliable bearing assessment using direct sensor tip measurements between 4,000 Hz and 20,000 Hz
  • Compares vibration levels with ISO-10816 severity scales
  • Allows you to view trending in Microsoft® Excel using pre-built templates
  • Features colored lighting system (green, red) and on-screen comments to indicate how much pressure needs to be applied to take measurements
  • Measures temperature with Spot IR Sensor to increase diagnostic capabilities
  • Holds and saves up to 3,500 measurements in on-board memory
  • Provides external accelerometer support for hard to reach locations
  • Allows you to export data via USB
  • Provides audio output for listening to bearing tones directly
  • Features built-in flashlight for viewing measurement locations in dark areas
  • Provides large high-resolution display for easy navigation and viewing
