The ESL-200C is a super bright, handheld, fully-featured LED stroboscope in a compact design. The ESL-200C 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.
Adjustable Flash Duration
For most applications standard flash duration works without adjustment. For ultra-high rpm or larger objects rotating with high surface speed, ESL-200 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.
- Includes NIST Traceable Calibration Certificate
- Dedicated Phase Adjustment Buttons on Keypad
- High efficiency LED solid-state light source
- Extended battery life of 5 hours continuous use at 6,000 fpm/rpm
- Pulse Width Modulation for sharp images at high speed
- Highly stable drift free operation
- Auto wide measuring range – up to 150,000 fpm/rpm (over 100,000 display flashes)
- Push button operation with x2 and ÷2 buttons for easy and precise adjustment
- Rugged aluminum housing – compact size – weighs only 1.2 lb (540 g)
- Easy-to-read 5 digit 0.47″ (12 mm) high LCD
- Store up to 19 flash rates in memory for records or quick retests (Restarts at the last flash rate)
- External trigger input and output
- Tripod mountable
- Kit includes stroboscope, AC Adapter/charger, and carrying case.
The External Trigger immediately synchronizes the stroboscope with a rotating object. The sensor is aimed at a ferrous target mounted on the drive shaft and triggers the strobe to flash each time the target passes the sensor. ET-1 is complete with sensor, cables and AC adapter. Ferrous target not-included.
