A Laser Tachometer is a non-contact instrument used to measure the rotational 
        speed of an object, such as a motor shaft, pulley, or gear, by detecting laser 
        reflections from a target. This device is commonly used in automotive, 
        manufacturing, and industrial settings to monitor and diagnose the performance 
        of machinery by providing precise readings of rotational speed in revolutions 
        per minute (RPM) or other units.
A laser tachometer is a valuable tool for professionals who need accurate, 
        reliable speed measurements to maintain, troubleshoot, and optimize rotating 
        equipment, improving safety and efficiency in a wide variety of applications.
