DT402-Z Auto-collimating Digital Theodolite
Effective working distance for indoor collimation reaches to 30mDirectional orientation error of auto - collimator part:5”
DT402 - Z contributes to aligning measurement and baseline precision measurement
With absolute encoder,angle measurements can be saved when power off
Compact design with wide LCD display facilitates numerical reading and operation
Minimum reading:1"/5"/10”or 0.2mgon/1mgon/2mgon
Lower power consumption,longer working time with one battery
