The reliable, repeatable, and precise method for measuring vibrations on bearings and other applications. Make confident maintenance decisions. The Fluke 805 is the most reliable vibration meter on the market for professional maintenance technicians who need repeatable measurements of overall vibration and bearing condition according to a severity scale. What makes the model 805 the best choice? This is not just a pen, but a measuring device for assessing overall vibration as well as specific variables like bearing condition and temperature for more detailed results. It features a combined vibration and force sensor tip, which helps to compensate for user-induced deviations (in terms of force or angle), thus achieving accurate, repeatable results. Using a four-level severity scale and an integrated processor, it measures bearing condition and overall vibration, providing corresponding results through easily understandable text messages (good, satisfactory, unsatisfactory, unacceptable). The sensor sensitivity is designed to read a wide frequency range (10 to 1,000 Hz and 4,000 to 20,000 Hz), covering most machine and component types. Additionally, the model 805 has a user-friendly interface that minimizes user input regarding the rotational range (RPM) and device type. The Fluke 805/ES is an external vibration sensor that is ideal for situations where it is either difficult or impractical to use the integrated vibration sensor of the 805 vibration meter.
