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. Tachometers are found in vehicles, generators, motors, bicycles and other rotating devices.

They are vital to the functioning of engines, generators, airplanes and other devices dependant on sustaining a certain rotational speed. Tachometers have traditionally been analog devices displayed by a pointer on a dial but are now migrating toward digital displays which are more accurate and easier to read.

This tachometer features 3 attachments for reading rotation speeds in all different circumstances. Simply make contact with the rotating shaft, device, motor etc. and the fast response will display the speed immediately. This means contact has to be made for a very brief period of time. This meter can spin at 20,000rpm without taking damage, making it great for testing even fast rotations. The 461891 Contact Tachometer User Manual is attached to this page to answer any further questions.
