VT805

Description

The reliable, repeatable, accurate way tocheck 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.

  • 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
