The NET-AX series of automated total stations for 3D monitoring includes NET05AX for 0.5-inch angle accuracy and NET1AX for 1-inch angle accuracy. The series has an auto-pointing feature that discerns the prism closest to the telescope center, even if multiple prisms or reflectors are in the field of view. In combination with the external control system, the total stations automatically search the predetermined area to quickly locate the position of the reflectors. The series is suited for measuring tunnel convergence and deformation, creating tunnel cross-section profiles and profile contours of tunnel walls.
