DT-900 Digital Pocket Stroboscope

Flash Rate: 30 - 12.500 RPM/FPM
and higher using harmonics

The DT-900 pocket stroboscope is a highly stable instrument for taking non-contact RPM measurements and inspecting moving parts by “freezing” or “slowing down” the action.

The gauge requires only one hand to operate, yet delivers performance comparable to much larger and heavier “pistol-grip” type models.

The DT-900 is ideal for industrial, laboratory, R&D and academic environments. Its small size and excellent performance provide superior convenience and value — at a reasonable price.


  • Easy to use with just one hand.
  • "LOW BAT"appears in the display if the energy becomes less.
  • Resolution of 0,1 Flashes per minute.
  • The changeable NiMH battery powers the stroboscope 2-2,5 hours.
  • NIST-Traceable calibration certificate & test report optionally available
  • "Universal" Battery Charger is supplied on "-UT" and "-UP" versions for use anywhere Worldwide on 100-265 VAC
