The Tachometer in the UGears STEM Lab Collection is a fully operational wooden model of a Tachometer, ready for you to assemble.

When the handle is rotated, movement is transmitted through a reducer, increasing the RPM and displacing twin weights in the centrifugal unit. The higher the RPM, the more centrifugal force separates the weights, shifting a movable axle with flywheel. A needle is fixed to the axle; the more the axle shifts (higher RPM), the more the needle moves, indicating higher speed rotation. Combine this with the UGears Variator to see just how fast you can go.
