DSL-300
Stroboscope

Measuring range 30 – 300000 flashes per minute (FPM)
Frequency range 0.5 – 5000 Hz
LED-hand held stroboscope for non-contact determination of revolutions, for monitoring moving parts and ascertain the oscillation frequency of running systems

Industrial stroboscope for battery operation with LCD display

Stroboscope with shock-proofed aluminium housing and 7 LED illuminants

Special Features

  • Stroboscope DSL-300 with easy to read LCD display
  • 7 LED illuminants assure a good illumination of the observing object
  • 1500 Lux at a distance of 20 cm and 6000 FPM
  • Double-flash-function (x 2) and half-rate-flash function (: 2) for easy and fast determination of the true flash rate
  • Adjustable flash duration time for best illumination
    – e. g. shorter flash period = tighter image
    – e. g. longer flash period = more brightening
  • Adjustable delay time of internal trigger signal and flash for optimal monitoring of motion sequences
  • Protection class IP65 (splash water and dust protection)
  • Battery operated

Additional function: Stroboscope DSL-300-T with trigger input and output

  • External trigger signal
    – Adjustable delay time in milliseconds (ms) between external trigger input signal and flash for optimal monitoring e. g. clock frequency or starting period of a machine
    – Phase shift between trigger signal and flash to make a rotating part visible in different degrees
    – Pulse divider to determine which input pulse should be used as signal for the flash

Standard Features

  • Selectable units Hz, rpm or FPM
  • One hand use
  • Handy, shock protected housing
  • Calibration report of manufacturers optional available
