1Overviewofthisproduct
A stroboscope tachometer is a measurement instrument to measure the speed (cycle) of rotating objects that rotate at a
constant speed, or moving objects that repeatedly operate at aconstant cycle.Whenthe rotation (motion) cyclematches with
the flash cycle whilethe strobe flash is periodically applied on a rotating or moving object, the rotating (moving) object image
appearstostandstill.Thisstroboscopetachometeristhenon-contacttype,andcanbeusedtoreadtheobjectfrequencywhen
such a still image appears. Also, a stroboscope can be used to make images of rotating or moving objects stand still or that
slightlymoveinordertoobservetheirappearanceinslow-motion.
Mainfeatures
●Wideflashrange–30to3000 FPM(flashesperminute)
●Emissioninsynchronizationwiththeexternaltriggerpulse
●PhaseShiftfunction.(PHAmode)
●Sealedstructuretopreventwateranddustfromentering.
