SKF TKRT20 Digital Tachometer

SKF TKRT20 Digital Tachometer 1 is a user–friendly and accurate digital tachometer utilizing laser or contact for measuring rotational and linear speed. Equipped with a laser and contact adapter, it offers excellent speed measurement versatility in five different modes. Additionally, the large angular range of ± 80° to target facilitates the easy measurement in areas where straight–line access is difficult. The laser optical system allows easy and quick speed measurement at a safe distance from rotating machinery.
