三木プーリの回転数指示計・回転速度計 製品一覧（回転監視・計測機器）

By installing it in the handle or mounting it on the shaft whose rotation you wish to measure, you can display the number of rotations. There are two types: the "weight-type," in which a pointer moves, and the "differential-type," in which the dial moves. Not only does it offer precise functionality, but its elegant appearance also enhances the machine's aesthetic appeal.
