The new PK2X hand-held Pocket Strobe? is convenient and accurate device to perform non-contact RPM measurements on rotating or reciprocating parts or components as well as a proven means for inspection of moving parts/machinery by “freezing” or “slowing down” the action. This stroboscopic effect is accomplished by matching the flash rate of the stroboscope with the repetitive rate (RPM) of motion of the target. A slow motion effect is accomplished with a slight mismatch of the relative speeds.
