Laser and contact tachometer with wide measurement capability

The TKRT 31 is an advanced, multi-functional digital tachometer. The large colour screen provides easy reading. Via the easy-button-control the user can quickly scroll through the menu and start operating.  The TKRT  uses laser or contact measurement to determine rotational speed, linear speed and distances. The device enables easy, quick measurement at a safe distance from rotational machinery. It has a wide speed range and a number of measurement modes. The TKRT 31 is supplied with a full set of contact adaptors.

  • User can measure a variety of functions, including rpm, Hz, m, feet/inches per minute or second, and length – all on a time interval
  • Compact device has large colour-backlit TFT display for maximum reading clarity. A full set of contact adaptors is included
  • Convenient to use: operated using one hand and works with either rechargeable or standard batteries.
  • Aimed at users in maintenance jobs, the device brings preventive maintenance to inspection of rotating equipment or machines
  • Large angular range enables easy measurement in areas where straight-line access is difficult
  • Laser sensor allows fast and easy measurement at a safe distance from rotating machinery. It has several measurement modes and a wide speed range, making it suitable for many applications
