Tachometers measure rotation speeds in a motor or other machine. The device measures revolutions per minute (RPM) and assist in diagnosing rotation speeds to avoid wear and damage of engines. Stroboscopes make cyclically moving objects appear to move slower so that they can measure the frequency of the object. Both devices are important to ensure that machines are running as they are intended and that they are operating safely and efficiently. Please browse our products to find which best suits your needs.
