Fluke 820-2 LED Stroboscope
The Fluke 820-2 LED Stroboscope helps users perform stop-motion diagnostics, investigate mechanical faults and support process or product research and development. Operators can observe the running speed of rotating equipment without stopping the machine or making physical contact. Its high-intensity seven-LED array delivers 4,800 lx at 6,000 FPM from 30 cm, while users can set the flash frequency from 30 to 300,000 FPM or 0.5 to 5,000 Hz.
Operators can also use the instrument as a strobe tachometer to measure rotational speed without reflective tape or a laser target. They can check shafts, belts, turbines, motors, gear teeth, pump vanes and other moving machine parts. The Fluke 820-2 LED Stroboscope also helps users identify parasitic oscillations, slippage, unwanted distortion and other motion-related problems during inspection.
Users can adjust the flash duration to produce sharper stop-motion images at high surface speeds and adjust the flash delay for detailed viewing of moving parts. The multi-line LCD and simple push-button controls, including x2 and ÷2 buttons, make adjustment straightforward. A rugged, one-metre drop-tested design and protective case help the Fluke 820-2 LED Stroboscope withstand practical use across a wide range of industrial environments.
Key Benefits
- Checks rotational speed without physical contact or reflective tape.
- Creates stop-motion views for inspecting fast-moving machinery while it continues to run.
- Wide flash frequency range supports both slower and very high-speed rotating equipment.
- Adjustable pulse duration can reduce motion blur and improve image sharpness at high speeds.
- Adjustable flash delay helps with viewing gear teeth, cutting surfaces, repeats and drifting images.
- x2 and ÷2 push-button controls allow quick frequency adjustment during testing.
- High-intensity solid-state LED lighting provides uniform flash characteristics across the operating range.
- External trigger connection allows the flash to be controlled from an external trigger source.
- Rugged, ergonomic construction and one-metre drop testing support reliable field use.
Common Applications
Fluke 820-2 LED Stroboscope is suitable for a range of testing, maintenance and inspection tasks, including:
- Checking turbines where speed changes frequently.
- Inspecting variable frequency drive motors where rotational speed may vary.
- Finding belt rotation speed and checking for belt slippage.
- Inspecting blades, pump vanes, compressor screws and gear teeth.
- Measuring rotational speed and investigating frequency.
- Carrying out slip measurements on rotating equipment.
- Identifying parasitic oscillations and unwanted distortion.
- Observing running shafts, speakers and other moving mechanical parts.
- Stop-motion inspection of rotating machinery without shutting it down.
Why Choose This Model?
The Fluke 820-2 LED Stroboscope combines a 30 to 300,000 FPM operating range with adjustable flash duration, adjustable delay, external triggering and non-contact strobe tachometer operation. Its seven-LED light source, multi-line LCD and rugged one-metre drop-tested construction make it well suited to industrial stop-motion diagnostics and rotational speed checks.
