TKRT 21

Multi-functional digital tachometer

The TKRT 21 is a multi-functional digital tachometer that uses laser or contact measurement to determine rotational and linear speeds.

The device allows fast, easy measurement at a safe distance from rotating machinery. It offers high speed and distance versatility in several measurement modes. In addition, it facilitates easy measurement when straight-line access is difficult. The TKRT 21 is supplied with a basic set of contact adaptors and can be used with either standard or rechargeable batteries.

  • Laser/contact measuring system
