Heavy duty, AC powered stroboscope

Part number: DT-311A | Request a quote
The DT-311A stroboscope is a great example of how Shimpo software is designed to give you the best experience possible when you need a stroboscope that provides the illusion of “stopped motion”. By adjusting the DT-311A’s flash rate, equipment appear to be standing still or in slow motion.

Accredited calibration/NIST traceable calibration certificate for Shimpo DT-311A Heavy duty, AC powered stroboscope might be available on request (for an extra charge). Please contact us for more info.

Shimpo Heavy duty, AC powered stroboscope: instrument description

Shimpo DT-311A it's an ideal instrument with own internal power supply for inspecting and measuring the speed of moving parts. DT-311A Stroboscope is reliable in the harshest environments thanks to its rugged metal construction. Inspecting and measuring the speed of moving parts is really quick and accurate using this portable digital stroboscope. During the tests by adjusting the strobe’s flash rate Shimpo DT-311A provides the illusion of “stopped motion”. Using in Tachometer mode, the instrument also measure rotational (RPM) or reciprocating (strokes per minute) speeds.

SHIMPO DT-311A Features

  • 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
