A handheld, non-contact laser tachometer that reads rotational speed from 2.5 up to 99,999 RPM by aiming its laser at a reflective marker on the spinning shaft from roughly 50-500mm away. Its large backlit LCD shows the live speed along with stored maximum, minimum, and average values, making it useful for checking motors, fans, spindles, and other rotating machinery without physical contact. Auto power-off and a low-battery warning keep it practical for field and workshop use.
