STROBOSCOPE OVERVIEW
Stroboscopes are used in various applications such as quality machine inspection and timing. At high-
speed or high frequency operation the human eye can not discern a single image of a moving object.
Stroboscopes are used to freeze these images by matching the speed of the moving object with short
duration flashes. An indicator or reference point such as a small tape or paint mark can be visually rotated
in any direction depending on the phase angle and flash rate it is subjected into.
The Shimpo DT-900 Techstrobe has many of the same capabilities as our DT-300 and DT-700 series
stroboscopes, without the size; these capabilities are incorporated in this unit so as to enjoy these features
with the mere touch of a button.
Check diagram of the parts overview to gain familiarity with this strobe.
