The DT-315A and DT-315A-2 are no longer available. They have been replaced by model DT-3015N
Flash Range: 40-35,000 RPM/FPM
The DT-315A is a rugged, battery-powered stroboscope designed for non-contact RPM measurement, inspection and observation of moving parts by “freezing” or “slowing down” the motion. The DT-315A provides power flexibility as in addition to its internal rechargeable battery it can operate from AC power.
