A tachometer simply measures the rotational speed of a shaft, wheel, pulley or a motor. This is a simple concept that can be difficult to accomplish, especially in an engine or confined space. Tachometers have developed into highly accurate, compact devices. Some models even feature laser or photo reading technology which offers non-contact readings and can be used on extremely fast rotations without worrying about damage or injury.

This meter is exclusively photo operated with an ability to measure 10 to 99,999 rpm. Simply attach the reflective tape to the wheel, shaft, disc or motor to be tested then start the rotation. Aim the photo measurement beam at the tape and the meter does the rest. Simple, compact and high accurate for safe non-contact rpm measurements.
