Fluke 820-2 LED Stroboscope Technical Data Rugged, compact and easy-to-use Investigate and observe potential mechanism failure with confi- dence on a variety of machinery, in a wide range of industries, without making physical contact with the machine. The Fluke 820-2 LED Stroboscope is a rugged, compact, portable strobe ideal for stop motion diagnostics, mechanical troubleshooting, and process or product research and development. The Fluke 820-2 LED Stroboscope is a simple, easy to Adjustable flash duration use tool to stop motion for measurement and diagnos- For most applications the standard tic purposes allowing you to: flash duration will work well with- Identify the running speed of rotating equipment out adjustment. In other applications without stopping the operation or making contact with higher rpm or larger rotating with machinery objects with high surface speeds, an Stop motion for diagnoses of parasitic oscillations, adjustable flash duration is needed. In flaws, slippage or unwanted distortions high speed applications, objects may move during the brief period of a single Measure speed of rotation or frequency of a rotating flash, resulting in a blurred image.

Key features: Common applications High intensity 7-LED array4,800 Lux 6,000 FPM/30cm for the 820-2 The Fluke 820-2 LED Stroboscope is more than just a High efficiency LED solid-state light source with tool to measure rotational speed of machinery without uniform flash characteristics allow for higher flash physical contact. It is also an excellent diagnostic tool rates30-300,000 FPM (flashes per minute) for a wide variety of applications: Digital pulse width modulation for exceptionally Belt driven machinesHVAC fans, pumps sharp images at high speeds Roller bearings, shafts, gear teeth or other machine Rugged, durable design utilizes solid-state LEDs components with no filaments, gases, hollow cavities, or Clutches and cogwheels glass(one meter drop) Foundationsresonance vibrations Quartz-accuracy control system provides high accuracy0.02 % ( 1 digit) Cable or piping wear or damage Multi-line LCD display Mixing and dosage processes Check the rotating speed of machinery without In addition, the stroboscope can be used as a strobe physical contact or need for reflective tape tachometer to measure speed instead of using a laser tachometer.
