LED stroboscopeThe ESL-200A is a super bright, handheld, fully-featured LED stroboscope in a compact design. The ESL-200A LED stroboscope is designed to measure the speed of rotating or cycling linear motion objects without contact or reflective tape, as well as freeze motion visually. Lifetime LED lights using pulse width modulation, encased in an aluminum housing and powered by a NiMH rechargeable battery, make this pocket strobe extremely durable and capable of high flash rates. The ESL-200 is an ideal inspection strobe for speed, motion and vibration analysis, such as rotating shafts, fans, cams, etc.

LED strobeAdjustable Flash Duration
For most applications standard flash duration works without adjustment. For ultra-high rpm or larger objects rotating with high surface speed, ESL-200A features adjustable flash duration.
For ultra-high-speed applications, objects may move during the brief period of a single flash, resulting in a blurred image. By decreasing flash duration, objects have less time to move and the image will appear sharper.
