The DT-326 is a portable stroboscope utilizing super bright LED’s in a robust, durable all metal design. The DT-326’s unique LED array provides an accurate, stable strobe light. The innovative LED design allows for a longer flash life – 5 times longer than traditional xenon flashtubes!

The DT-326 is designed for Speed (RPM) and Frequency (Hz) measurements in motion and vibration analysis. It is ideal for predictive and preventive maintenance applications such as: motors, shafts, roto-gravure printing, extruders, blow molding, wire lettering and striping, engraving, pulse jets, water jets, fans, cams, gear teeth, belt inspections, audio/speakers, fuel injectors, vibration analysis and cutting blade timing and sharpness. With its intuitive “ONE HAND” controls, vast adjustable flash rate, superior brightness, focus control, silent operation, AC/DC power flexibility, the DT-326 LED Stroboscope provides a superior value in a compact, ergonomic package.


  • Wide Flash Range: 60-120,000 flashes per minute, can be applied to meet almost any HIGH-SPEED application
  • Phase Shift: Advance or retard flash timing for viewing gear teeth, cutting surfaces, repeats or “drifting” images
  • Ratio Control (Flash Pulse Duration): Adjustable Flash Pulse duration achieves sharper images for critical inspection
  • All Metal Construction: Durable, comfortable, hand-held, fixed or swing arm mounted
  • ECO Mode: Brightness control extends battery life
  • Input/Output Interface: Input sensor triggers or Output synchronization controls
  • AC/DC Operation: AC adapter for continuous use or (4xAA batteries) for maximum portability
  • Includes Traceable Calibration Certificate
  • 2 Year Warranty
