DT-315A Stroboscope

DT-315A StroboscopeDT-315A Portable Stroboscope with Rechargeable Battery

The DT-315A heavy duty, battery powered stroboscope possesses the same great features of the DT-311A with the added convenience of total portability via its own internal power supply. The quick recharge battery lasts up to four hours of full continuous usage with its high intensity flash rate. The DT-315A provides power flexibility by utilizing either its rechargeable internal, batteries or AC line-power when plugged into the included AC adapter/charger unit. These features make the DT-315A ideal for quality inspection and preventitive maintenance of automated motion equipment.


  • Internal, fast-charge rechargeable battery supply
  • Aluminum construction provides exceptional durability
  • High polish and focused reflector eliminates “blind” viewing areas
  • 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
  • High accuracy ( ±0.01% of reading ) is ideal for QC inspection and process control
  • Synchronous output enables strobe to drive other strobes
  • Flash timer control conserves flash tube life
  • Easy tri-pod or permanent mounting with integral mounting thread
