Handheld device for measuring rotational speeds, distances, and events. Using a laser unit, rotating parts can be measured very precisely and contactlessly, even in daylight conditions. The display is shown on a 5-digit LCD. The measured data can be displayed as rotational speed in RPM, frequency in Hz, speed in m/min, in/min, yd/min, distance in meters, inches, yards, or as an event counting function. The device features a min/max and average memory for the last 40 measurements.
