Description
Overview
The Fluke 805 Vibration Meter is a handheld vibration screening instrument designed for maintenance teams, plant engineers, service technicians, and reliability professionals who need a practical way to check bearing condition and overall machine vibration. It is built for frontline mechanical troubleshooting, where technicians need repeatable readings that can support go/no-go maintenance decisions without requiring a full vibration analysis system for every inspection point. Fluke describes the 805 as a vibration meter for checking bearings and overall vibration, with severity-scaled readings for bearing condition and overall vibration.
For industrial buyers, the Fluke 805 is especially useful when a maintenance program needs a consistent vibration screening tool for rotating equipment such as motors, pumps, fans, compressors, blowers, gearboxes, and similar machinery. It measures overall vibration in the 10 Hz to 1,000 Hz range and uses Crest Factor+ technology for bearing assessment in the 4,000 Hz to 20,000 Hz range. This makes the Fluke 805 Vibration Meter suitable for routine condition checks, preventive maintenance routes, baseline comparison, and early identification of vibration changes that may require further inspection.
Unlike simple vibration pens, the Fluke 805 is positioned as a meter that combines overall vibration, bearing condition, and temperature information into a more complete screening workflow. Fluke states that the product includes a combination vibration and force sensor tip designed to compensate for user variance such as force or angle, helping improve repeatability between technicians and measurement rounds. The four-level severity scale displays easy-to-understand status levels—Good, Satisfactory, Unsatisfactory, and Unacceptable—so maintenance teams can prioritize follow-up actions quickly.
The Fluke 805 also supports practical field use. It includes a Spot IR temperature function, USB data export, Microsoft Excel trending templates, onboard memory for up to 3,500 measurements, a built-in flashlight, a large high-resolution display, and support for an external accelerometer for hard-to-reach locations. These features help maintenance teams collect vibration data more consistently, compare readings over time, and document asset condition for planning, shutdown preparation, and procurement decisions.

Applications
The Fluke 805 Vibration Meter is suitable for maintenance and reliability teams that need a fast, repeatable method to screen rotating machinery. It can be used during routine inspection routes to check whether vibration levels remain within an acceptable condition range or whether the asset requires further investigation. Because it provides both bearing condition and overall vibration readings, it is useful for identifying changes that may be associated with bearing wear, imbalance, looseness, misalignment, or other machine health issues that require deeper analysis.
Typical application areas include motor vibration checks, pump inspection, fan and blower maintenance, compressor condition screening, gearbox monitoring, production-line maintenance, building services maintenance, and general mechanical troubleshooting. The meter’s severity scale can help technicians and supervisors communicate asset condition in a consistent way, especially when vibration expertise varies across the maintenance team. Fluke also provides guidance and resources for using the 805 as part of vibration, alignment, and diagnostic tool workflows.
For procurement teams, the Fluke 805 is a practical choice when the requirement is not a full vibration analyzer but a portable vibration screening meter for day-to-day equipment checks. It supports maintenance records through USB export and Excel-based trending templates, allowing teams to track changes in vibration readings over time. This makes it appropriate for preventive maintenance programs, spare-parts planning, maintenance reporting, and condition-based maintenance initiatives.
