Pinpoint accuracy combined with measurement versatility

The SKF Multi–functional Digital Tachometer TMRT 1 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 yds per minute or second,
- length or revolution counting, or
- time interval
Wide speed range and the various measurement modes make the TMRT 1 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 TMRT 1 can also be equipped with remote laser sensor, which is optionally available
