Description
Laserman DT402 Universal Digital Theodolite
DT400 series Electronic Theodolite applied absolute encoders system for digital angle measurement, don’t need rotate telescope to start angle measurement.
It can achieve measurement, calculating, display and memory etc. by means of computer technology
It can display measuring results of horizontal and vertical angle at the same time
Vertical angle can switch to zenith angle or grade and so on
DT400 Series Theodolite:
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
Repeated angle program which carries out continuous measuring and average calculating to get high accuracy angle value
Rechargeable battery and AA battery are available
Lower power consumption, longer working time with one battery
