Fluke 805

Fluke 805 – Overview

The Fluke 805 is a frontline mechanical maintenance tool that gives reliable, repeatable vibration and bearing checks. It combines a specially designed sensor tip that reduces user variation, a four-level severity scale, and onboard diagnostics with IR temperature measurement. It’s ideal for technicians who need quick “go/no-go” assessments of machinery without deep vibration analysis expertise.

Key Features

• Measures overall vibration (10-1,000 Hz) plus high-frequency bearing (CF+) from 4,000-20,000 Hz

• Four severity levels: Good, Satisfactory, Unsatisfactory, Unacceptable

• Uses “Crest Factor+” (CF+) algorithm for improved bearing fault detection

• Spot IR temperature measurement to check bearing temperature

• On-board memory for up to ~3,500 measurements

• USB export of data for trending in Excel

• Lighted display and color-coded feedback to indicate measurement quality/pressure

• Audio output to listen to bearing noise directly

• Rugged, easy-to-use interface

Technical Specifications

• Measurement range: 0.01 g up to 50 g

• Sensitivity: approx. 100 mV/g ±10%

• Resolution: 0.01 g

• Accuracy: ±5% of measured value at ~100 Hz

• Vibration limit: 50 g peak (~100 g peak-to-peak)

• Signal-to-noise ratio: ~80 dB

• Sampling rate: 20,000 Hz (low frequency), 80,000 Hz (high frequency)

• Temperature range (IR sensor): -20 °C to +200 °C

• Memory capacity: ~3,500 readings

• External interfaces: USB (mini-B), audio output jack, external sensor connector

• Battery type: 2 × AA (Lithium Iron Disulfide or alkaline)

• Battery life: ~250 measurements per charge/set of batteries

• Size (L × W × H): ~24.1 × 7.1 × 5.8 cm

• Weight: ~0.40 kg

• Operating temperature: -20 °C to +50 °C

• Storage temperature: -30 °C to +80 °C

• Humidity: 10-95% non-condensing

• Altitude: up to 3,048 meters (≈ 10,000 ft)

Applications

• On-site screening for bearing health and overall vibration in motors, pumps, gearboxes

• Trending machine health over time with simple go/no-go metrics

• Maintenance checks in dark or hard-to-read locations using built-in lighting and audio cues

• Use by technicians with limited vibration analysis experience

Why Choose Fluke 805

• Minimizes variation in readings via sensor tip design and CF+ tech

• Good memory size and USB export allow trending without extra tools

• IR temperature adds useful diagnostic info in same handheld unit

• Durability, ease of use, and understandable severity scale make it effective for routine checks
