Attach it to the shaft whose rotation count you wish to measure, and it will display that count. For the weight-type models, we offer sizes 28, 38, 53, and 75 based on outer diameter; sizes 28 and 38 come with an integrated handle. For sizes 53 and 75, you will need to design the handle yourself or select a handle set model. A wide range of rotation ratios is available.
