Kolida Theodolite DT-02LL Up and Down Laser Theodolite

Kelida DT-02LL Laser Electronic TheodoliteAdopting high-end impedance reduction circuit optimization design; The world's first CCD as a receiver; The new coaxial confocal visible laser electronic theodolite, the KELIDA DT-02LL laser electronic theodolite, can observe and correct different axis errors between the laser and the sighting axis at any time, which is very practical and easy to use. Kelida DT-02LL LaserElectronic TheodoliteDouble sided LCD Chinese display, convenient, fast, practical, and accurate. The Kolida DT-02LL laser electronic theodolite uses radial readings for both horizontal and vertical disks to ensure a 2-second accuracy; Encoding angle measurement method, angle measurement accuracy of 2 seconds, electronic bubble compensation accuracy of 1 second, compensation range of ± 4 ', with laser alignment and laser pointing.
