Stroboscope for speed testing, measures 50-30,000 rpm with xenon lamp and 0.05% accuracy

A handheld stroboscope or strobe tachometer with trigger functionality. This easy-to-use portable digital stroboscope gun features high / low range selection and push-button rate control to scale the flash rate slower (x1⁄2) and faster (x2). In addition, two knobs allow coarse and fine adjustment of the flash rate. When the speed of a moving object matches the flash rate of the strobe, the moving object appears to be standing still. With a slight adjustment, movement can be viewed in apparent slow motion. Slow motion makes it easier to visually inspect the process in action. However, these visual illusions can be disorienting. Take necessary safety precautions to avoid accidental contact with moving objects.
