Multi–functional digital tachometer
Pinpoint accuracy combined with measurement versatility
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
