Leica Absolute Tracker AT901

Leica-AT901

The Leica Absolute Tracker AT901 is ideal when 'up-close' measurement isn't an option. It is equipped with PowerLock vision technology which automatically locks onto any moving target - no more worrying about broken beams. It locks on to the target as soon as it is within view of the sensor.

The AT901 laser tracker sets the benchmark for large scale precision measurements such as windmill blade inspection, aerospace components or industrial machinery alignment. Options allow it to support hand-held wireless probing, hand-held contactless scanning, and full machine control abilities. It can also be used with a standard corner cube, which enables the measurement volume to go past 525 ft.
