Fluke 820 LED Stroboscope, ±0.02 % Accuracy

Fluke LED Stroboscope, ±0.02% Accuracy, 240g Weight - Fluke-820-2

This LED stroboscope is a compact, portable tool for non-contact measurement and stop-motion inspection of rotating and oscillating machinery. Designed for industrial environments, it allows users in automation, electronics, electrical and mechanical fields to observe motion, diagnose oscillations, and read markings on moving parts without interrupting operation.

Features & Benefits

• Flash range 30 to 300,000 FPM enables very low to very high-speed observation
  High-intensity 7 LED array delivers 4,800 lx at 6,000 FPM for clear imagery
  Adjustable Pulse width yields sharper images on high-surface-speed parts
  Accuracy ±0.02% supports precise RPM and frequency analyses
  External trigger connector allows synchronised control with processes
  Durable construction withstands 1m drops for field durability

**Applications**

• Suitable for checking belt slippage on HVAC fans and pumps
  Ideal for inspecting gear teeth meshing and clutch behaviour
  Used for RPM measurement on variable-frequency drive motors
  Can be used for monitoring mixing and dosing operations
  Used with speakers and rotating lab equipment for frequency studies

What environmental limits affect on-site use?

It operates between 0–45°C and is rated for non‑condensing humidity with defined relative humidity limits by temperature to maintain performance.

How is timing adjusted for viewing repeat patterns or drifting images?

Delay and Pulse duration are adjustable in microseconds or degrees to advance or retard flashes for repeat alignment.

What light characteristics influence Visual diagnostics?

The LEDs emit at approximately 6,500 K and use pulse‑width modulation to reduce motion blur at high flash rates.

How is measurement resolution presented across the flash range?

Resolution varies: 0.1 increments at lower FPM/Hz ranges and 1 increment at higher frequencies for detailed readouts.
