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 stroboscopes. Unique to the ST-5100 is an
auto-speed detection laser that translates speed sensed direct-
ly over to the flash rate of the LED’s simplifying operation. Con-
taining 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 anal-
ysis applications. It is ideal for predictive and preventive mainte-
nance 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.
