DT-315P Stroboscope

DT-315P StroboscopeSeries DT-315P Stroboscope for Harsh Usage

The DT-315P Battery Powered, NEMA 4X Stroboscope for Harsh Applications. The DT-315P is a rugged, sealed NEMA 4X (IP65) Stroboscope suitable for working in areas without AC power. The DT-315P works just like the DT-315A battery operated strobe. Equipped with Phase shifting in angle of delay (0-359 degrees) and flash time delay, (0-300 mSEC) the DT-315P is engineered for checking timing and wear on rotating and reciprocating machinery. With its rugged, metal body and NiCd rechargeable battery, the DT-315P provides the maintenance and quality professional a rugged, accurate strobetach for inspection on presses, conveyers, gear reducers, chain drives, fuel injectors, paint spray patterns, and many other harsh environment, industrial applications.


  • Extruded aluminum, NEMA 4X construction: Extraordinary durability yields long service life
  • Internal battery supply: Lightweight; enables easy portability
  • Repeatable accuracy (± 0.01% of reading): Fully meets the strictest tolerances
  • Phase shift (in degrees of delay time): Enables visual analysis of rotating/reciprocating objects through all points of motion/time/angle
  • Flash timer control: Prolongs flash tube life
  • Manual flash controller knob: Permits easy/accurate adjustments to flash rate
  • Continuous duty cycle: Eliminates downtime waiting for unit to cool
  • Highly polished focused reflector: Prevents “blind” viewing areas
