SD Model (Differential Type)
Attach it to the shaft whose revolutions you wish to measure, and it will display the number of revolutions. In the differential type, when the rotating shaft turns, the dial rotates in the same direction. You can freely choose between dials that increase clockwise or counterclockwise. There are no restrictions on the mounting direction, and you can choose from outer diameters of 50 mm or 100 mm.
