The ST-5100 is a portable, light-weight stroboscope with trigger light activation that utilizes 21 super-bright CREE High Powered LED lamps. The ST-5100’s LED array provides a bright, stable strobe light over a wide measurement range with a lifetime far exceeding xenon-lit stroboscope. Unique to the ST-5100 is an auto-speed detection laser that translates speed sensed directly over to the flash rate of the LED’s simplifying operation. Containing a rechargeable lithium battery, a single charge is able to last up to a full 5 hours of operation. The ST-5100 is designed for speed and frequency measurements in motion and vibration analysis applications. It is ideal for predictive and preventive maintenance applications such as motors, shafts, roto-gravure printing, extruders, blow molding, wire lettering, and striping, engraving, pulse jets, water jets, fans, cams, gear teeth, belt inspections, fuel injectors, vibration analysis, audio speaker analysis, spindle spinning, cutting blade timing and sharpness, plus many more in the printing, packaging, textile, automotive, cable, mining, steel, chemical, optical, medical and shipbuilding industries.
