Leica TM6100A

Leica TM6100A theodoliteCost-efficient large scale measurement with absolute reliability – industrial theodolites by Leica Geosystems (a Hexagon company) meet the highest standards even under the toughest conditions. The extreme measurement volume of over 500 meters makes a theodolite the first choice for the inspection and assembly of large components. Industrial theodolites have long since been the standard in the optical compensation of satellites and navigation systems. Open-system architecture makes the development of user-specific software a convenient option. The non-contact, autocollimation function provides industrial theodolites from Hexagon Metrology with a legendary degree of precision.

Leica Geosystems’ Industrial Theodolites are known around the world for being the most accurate, with the highest angular accuracy of 0.5”. These autocollimating theodolites have set the benchmark with unrivalled precision and superb optics.

Leica Geosystems has redesigned the direct drive technology for the TM6100A, using the same Piezo technology that is used in the Leica TDRA6000 and the Leica Absolute Tracker AT401. The drives offer the stability of manual drives, the flexibility of fully automated motorized drives and still allow for sub micron level fine positioning. The fine adjustment knobs on the Leica TM6100A are strategically positioned to help make measuring in difficult situations easier. Because there are no gears with this technology, the direct drives require almost no maintenance and are nearly silent.

The Leica TM6100A enables you to work more than a full day without having to charge or change the battery. The color touch screen remains clearly visible at all times, allowing you to take the theodolite to any location. The intuitive user interface allows minimal training before doing basic measurements and calibrations to the sensor. The interface offers function keys that can be set for specific procedures, six of the 12 are already pre-set with the most commonly used procedures.
