Description

Helps to detect abnormal rotating and linear speeds

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.

  • User can choose to measure a range of attributes, including: rpm, Hz, m, ft or in per minute or second, and length
  • Compact, with large LCD display. Operated using one hand, it includes a basic set of contact adaptors. Runs on standard or rechargeable batteries.
  • Aimed at maintenance staff, it is well suited for inspecting rotating equipment and machinery – using preventive maintenance to optimise operations
  • Laser sensor allows fast and easy measurement at a safe distance from rotating machinery. Usable in many applications, as it has several measurement modes and wide speed range
  • Enables easy measurement in areas where straight-line access is difficult
