LED Stroboscope

Fluke 820-2

 LED Stroboscope

The Fluke 820-2 LED Stroboscope helps you identify the running speed or rotating equipment without stopping it or making contact, enabling you to easily diagnose parasitic oscillations, slippage, or unwanted distortions on a range of machines commonly used on mine sites.

The Fluke 820-2 also includes a digital pulse width modulation feature for exceptionally sharp images on high-speed machinery, such as grinding mills and belt conveyors, so that the rotating speed can be easily monitored.

  • 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 at 6,000 FPM/30cm

  • Provides a high-efficiency LED solid-state light source with uniform flash characteristics that allow for higher flash rates of 30-300,000 FPM (flashes per minute)
