DT-725 Stroboscope

DT-721/725 StroboscopeDT-725 Portable, Light Weight Stroboscope with Rechargeable Battery

The DT-725 possess many of the same features as the famous DT-300 Series Stroboscopes, but are lighter in weight. Constructed of strengthened high impact plastic, these rugged units are exceptionally reliable and withstand the same harsh conditions as more expensive units. Employing its unique phase shifting feature, the DT-725 “freezes” rotating or reciprocating machinery for visual inspection of covered gear teeth, shafts, oil/fuel/ink injector patterns, and print media; all without stopping production.

These features make the DT-725 ideal for quality inspection and preventive maintenance of automated motion equipment. Units can be ordered separately or as a convenient kit.


  • Bright LED Display Aids viewing in poorly lit areas
  • Light Weight Design
  • External trigger allows unit to be automatically synchronized with equipment
  • Continuous duty cycle eliminates need to shut down for cooling
  • Phase shift allows visual analysis of rotating/reciprocating objects
  • Easy adjust flash rate controller dial
  • Synchronous output enables strobe to drive other strobes
  • Easy tri-pod or permanent mounting with integral mounting thread
  • Internal, fast-charge rechargeable battery supply
