FLUKE 820-2 | LED strobe with adjustable flash duration

Manufacturer number: FLUKE-820-2

FLUKE 820-2 | LED strobe with adjustable flash duration.

  • Bright LED array with 7 LEDs - 4800 lux at 6000 flashes per minute / 30 cm
  • Highly efficient LED solid light source with constant flash properties to achieve higher flash frequencies - 30 to 300,000 flashes per minute
  • Digital pulse width modulation for exceptionally sharp images at high speed
  • Robust, hard-wearing design with solid LEDs without filaments, gases, cavities or glass (survives the fall from a height of 1 m)
  • Quartz control system ensures high accuracy - 0.02% (± 1 digit)
  • Multi-line LCD display
  • Testing the speed of machines without physical contact and without a reflective tape
  • Premature or delayed flashing for viewing gears, cut surfaces, repetitions or "drifting" images
  • Easy setting through user-friendly button operation with the "2x" and "÷ 2" buttons

820-2 | LED strobe with adjustable flash duration

The FLUKE LED stroboscope 820-2 is more than just a tool for measuring the speed of machines without physical contact. It is also an excellent diagnostic tool for numerous applications:

  • Belt-driven machines - fans in heating, ventilation and air conditioning systems, pumps
  • Ball bearings, shafts, gears or other machine parts
  • Clutches and gears
  • Foundations - resonance vibrations
  • Wear or damage to cables or pipes
  • Mixing and dosing processes

The Fluke LED Stroboscope 820-2 can be used instead of a laser tachometer as a stroboscope tachometer for speed measurement. To use the stroboscope, the component to be measured must be visible and provided with a label that can be used as a reference point. A strobe tachometer is a helpful tool because you don't always have access to the machine shaft to stick on reflective tape for using a laser tachometer. And you also can't always make contact with the moving shaft to use a contact tachometer. With a stroboscope you can measure shaft speeds down to 30 fpm (flashes per minute).

Areas of application:

  • Variable speed turbines with frequent speed changes
  • Motors with frequency converters that run at different speeds, but the speed of which does not change frequently
  • Determination of belt speed and belt slip
  • Examination of machine components - fan blades, pump blades, compressor screws and gears
  • Speed measurement and frequency analysis
  • Slip measurement
