LED Stroboscope |
The ESL-20 has been replaced by the new and improved ESL-100. Please click here to view the new model 
Measuring Range: 6 - 120,000 FPM
The brightest, fully featured LED strobe in a trim, efficient design. The ESL-20 series LED stroboscope incorporates 96 separate high-powered LEDs designed to measure the speed of rotating or cycling linear motion objects without contact or reflective tape, as well as freeze motion visually.
 Using a rugged aluminum housing and the latest technology, it’s compact size, NiMH rechargeable battery and lifetime LED lights make it a perfect choice for use anywhere on the factory floor. The ESL-20 is ideal for speed, motion and vibration analysis, such as rotating shafts, fans, cams, etc |
 Store up to 19 flash rates in memory for records or quick retests (Restarts at the last flash rate) | | Power-SAVE feature automatically turns off the LEDs if no user-changes are detected on the keypad (can be disabled if desired) | | Operates from internal NiMH Battery or via external AC-Adapter (provided) | | Push button operation with x2 and ÷2 buttons for easy and precise adjustment along with phase shift | | NIST-Traceable Calibration Certificate provided |
| | Battery runtime of approx. 10 hours on a single charge. Supplied with an automatic charging system that prevents overcharging and damaging the battery | | 350 Lux brightness (measured at 6000 fpm at a distance of 50 cm) | | 2 year warranty | | Includes an external trigger input for flash control via an external sensor or controller as well as a trigger output | | ET-1 External Trigger Kit is optionally available includes external sensor and AC-Adapter for auto synchronization of strobe |
|
at 30 cm Distance, 6000 flashes/min (FPM)
|
| | | | Supplied in foam-fitted carrying case with LED Stroboscope, AC-Adapter/Charger, instruction manual and NIST-Traceable Calibration Certificate. |
 |
 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 |
