Fluke 805-NLA Hand Held Vibraiton Meter

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 Fluke 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.


Features and Benefits

  • Innovative sensor design helps minimize measurement variations caused by device angle or contact pressure
  • Consistent data quality at both low and high frequency ranges
  • Four-level scale indicates severity of problems for overall vibration and bearing condition
  • Exportable data via USB
  • Trending in Microsoft® Excel using built-in templates
  • Overall vibration measurement (10 Hz to 1,000 Hz) for acceleration, velocity and displacement units of measurement for a wide variety of machines
  • Crest Factor+ provides reliable bearing assessment using direct sensor tip measurements between 4,000 Hz and 20,000 Hz
  • Colored lighting system (green, red) and on-screen comments indicate how much pressure needs to be applied to take measurements
  • Temperature measurement with Infrared Temperature Sensor increases diagnostic capabilities
  • On-board memory holds up to 3,500 measurements
  • Audio output for listening to bearing tones directly
  • External accelerometer support for hard to reach locations
  • Flashlight for viewing measurement locations in dark areas
  • Large screen with high resolution for easy navigation and viewing
