Product overview: Fluke 805 Vibration Meter

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

Rated 1 out of 5 by from overall frustrating experience We have been using this devices since 2016. we have had to replace a device every two years due to issues with the battery, software on the device, wear and tear and overall difficulty of inputting and collecting information on the device. Setup of the functions on the device is difficult and long, with the base model you cannot delete items saved to the device without deleting all information into the device (you can delete specific measurements on the device, more on this later.). If you are using the pressure sensor portion of the device it will commonly take 2 minutes to download information. saving information is difficult due to how the menu is setup. as you save more information to the device the slower it gets making it less than ideal if you have to trend multiple motors. if you create a list by accident, you cannot delete that specific list without permanently deleting everything on the device. if maintenance is required due to wear and tear it has to be sent to the United States for repairs and calibration leaving us without a device to use for 2 months at a time. most of the repair costs are more than the device and we just have to buy a brand-new device! Device is not accurate using the pen when comparing it to a external magnetic sensor. Batteries regularly move when the pen is being used causing the device to die mid read Batteries have to be replaced on a monthly basis if alkaline and every 3 months if lithium.

Rated 1 out of 5 by from Just a vibration pen This tool in reality is so much less than what it's advertised as.

Rated 1 out of 5 by from Data entry is a real pain. To be able to graph trends on a machine, you must give the machine a name, and all of the read points must also have their own name for that machine. I have hundreds of these to do, and it is incredibly difficult to enter on this meter. Fluke does not have any support software to interface computer entry. The meter makes quality reads, but the software has locked up 4 times in two days.

Rated 1 out of 5 by from Battery life ruins it! When the 805 works it's great but the battery life is beyond abysmal, lithium, NiCd, NiMH they all get gobbled by the meter after 6 or so measurements! In fact brand new batteries get put in the same day and even though the meter is fully off they are down to 2 bars on the next power up! Could I possibly have a bad unit, I hope so because if this is the usual battery life the meter is about useless!

Rated 4 out of 5 by from Missing external sensor information Great product, though it does not provide elementary information on what type of external sensors it supports.
