Multi–functional digital tachometer

Pinpoint accuracy combined with measurement versatility

Multi–functional digital tachometer TKRT 20
Multi–functional digital tachometer TKRT 20
The Multi–functional digital tachometer TKRT 20 is a user–friendly and accurate digital tachometer utilising laser or contact for measuring rotational and linear speed. Equipped with a laser and contact adaptor, 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.
  • With this digital tachometer the user can select to measure:
    - rpm, rps, m, ft or yards per minute or second,
    - length or revolution counting, or
    - time interval
  • Wide speed range and the various measurement modes make the TKRT 20 suitable for measuring speed in many applications
  • Large angular range of ± 80° to target facilitates easy measuring in areas where straight–line access is difficult
  • The large inverting LCD display facilitates easy reading even when pointing the unit down into the machinery
  • Compact design; one–hand operated instrument
  • Supplied in carrying case for protection and portability 
  • The digital tachometer TKRT 20 can also be equipped with remote laser sensor, which is optionally available
