The DT-315AEB Portable Stroboscope with Re-
chargeable Battery incorporates a robust, extruded alumi-
num housing with a precise, repeatable accuracy allowing it to be
the solution for the most demanding applications. A truly portable
unit, the DT-315AEB operates independent of line power via an ex-
terior battery pack that can be carried with a convenient shoulder
harness or set down to allow the operator full movement for visual
inspection. When fully charged, rechargeable batteries power the
strobe for approximately four continuous hours.
DT-315AEB Portable Stroboscope
Easy Operation Control
Features
• Extruded aluminum construction: Extraordinary durability yields long service life
• External 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
• External trigger: Allows synchronization of the flash rate with the motion of the rotating machinery
• Continuous duty cycle: Eliminates downtime waiting for unit to cool
• Highly polished focused reflector: Prevents “blind” viewing areas
