SKF Maintenance and Lubrication Products

Pinpoint accuracy combined with measurement versatility
SKF Multi–functional Laser / Contact Tachometer TMRT 1
The SKF TMRT 1 is a user–friendly and accurate 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.
• The user can select the following 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
SKF 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 laser optical system allows easy and quick measurements at a
safe distance from rotating machinery
• 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 TMRT 1 can also be equipped with a remote laser sensor, which
is optionally available
