Leica Geosystems T-Probe II, the second generation of the “Walk-Around” armless wireless probing of hidden, hard-to-reach points and measuring of up to 9 cars in one setup with minimal setup times, sets new standards by increasing accuracy, offering a ten-fold increase in point acquisition rate and providing user-assignable multi-function buttons. Small, light, user-friendly, and more accurate than any other hand-held probe in the world, the Leica T-Probe II gives you more than 6 Degrees of Freedom: It gives you the right way to measure. Leica T-Probe reaches up to 30m (98 ft.) in any dimension.

Detailed information
The uncertainty specified below is achieved with Leica T-Probe II (110 mm stylus in mount 1) and a measurement mode of 1s per point under stable environmental conditions.
The measurement uncertainty of 3D points “U3D” is defined as the distance between a measured point and the nominal position of that point. This measurement uncertainty is specified as a function of the distance between the Laser Tracker and the measured point.
The measurement uncertainty of spatial length “UL” is defined as the deviation between a measured length and its nominal value. This measurement uncertainty is specified as a function of the shortest distance between the Laser Tracker and the measured length. The length can be up to 6m and is positioned perpendicularly to the laser beam (Leica T-Probe held in constant orientation).
Measurement uncertainty of sphere radius “UR” is defined as the deviation between a measured sphere radius and its nominal value. This specification assumes a reference sphere with a radius between 10mm and 50mm. This measurement uncertainty is specified as a function of the distance between the Laser Tracker and the measured sphere (Leica T-Probe held in constant orientation).
Measurement uncertainty of 3D Point (2 Sigma)- U3D = 100µm for < 7m (0.00394in for < 23ft)
- U3D = 30µm + 10µm/m for > 7m (0.00118in + 0.00012in/ft for > 23ft)
Measurement uncertainty of spatial length (2 Sigma)
- UL = ± 60µm for < 8.5m (± 0.00236in for < 27.9ft)
- UL = ± 7µm/m for > 8.5m (± 0.00008in/ft for > 27.9ft)
Measurement uncertainty of sphere radius (2 Sigma)
- UR = ± 20µm + 2µm/m (± 0.00079in + 0.00002in/ft)
