  • FLUKE 820-2 LED Stroboscope

    # 820-2

    • Includes digital pulse width modulation for exceptionally sharp images at high speeds
    • Provides rugged, durable design that uses solid-state LEDs with no filaments, gases, hollow cavities, or glass; (1 meter drop tested)
    • Features quartz-accuracy control system for high accuracy–0.02% (+/- 1 digit)

    Key features

    • Rugged, compact, easy to use stroboscope for checking the rotating speed of machinery without physical contact or the need for reflective tape
    • Features high-intensity 7-LED array—4,800 Lux @ 6,000 FPM/30cm
    • Provides a high-efficiency LED solid-state light source with uniform flash characteristics that allow for higher flash rates—30-300,000 FPM (flashes per minute)

    Product overview: Fluke 820-2 LED Stroboscope

    Investigate and observe potential mechanism failure with confidence

    Identifying the running speed of rotating equipment can be difficult, but the Fluke 820-2 LED Stroboscope simplifies the process allowing you to perform stop motion diagnostics without actually stopping, or making contact, with the machine you are working on. Whether you are trying to diagnose parasitic oscillations, slippage, or unwanted distortions, the 820-2 LED Stroboscope is the ideal frontline troubleshooting, process or product research and development tool.
