The LUDECA SHAFTALIGN shaft alignment tool has a TFT backlit color display for simplicity of operation and precise measurement. Its intuitive auto-flow capability guides users to obtain the desired machinery alignment condition. An “Active Clock” measurement mode automatically collects the laser coordinates for the corresponding shaft position. Only 3 readings over a rotational angle of less than 70° are required to achieve alignment. A built-in light sensor optimizes screen image quality and power management.
