The brightest, hand held, fully featured LED stroboscope in a compact design. The ESL-100 series 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 portable strobe extremely durable and capable of high flash rates. The ESL-100 is an ideal inspection strobe for for speed, motion and vibration analysis, such as rotating shafts, fans, cams, etc.


ESL-100 adjustable flash duration

Adjustable Flash Duration

For most applications standard flash duration works without adjustment. For utra high rpm or larger objects rotating with high surface speed, ESL-100 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.
