The SKF TMRT is a user–friendly and accurate tachometer utilizing laser or contact for measuring rotational and linear speed. TMRT 1 is equipped with laser and contact adaptor, the tachometer offers excellent speed measurement versatility in five different modes. Additionally, the large angular range of ± 80º 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 safe distance from rotating machinery. Works best with reflective tape target (included).
