Deskripsi :
Digital Theodolites DT-200/200L
- Longer battery powering duration
Longer battery powering durations using alkaline batteries. Continuous
angle measurement for 150 hours (DT-213). Laser continuous angle
measurement for 45 hours.
- Absolute encoder is used
Detection of 0° position is no longer needed. Stable, high-accuracy measurement.
- Laser pointer
The laser pointer is injected in collimation direction by simply
operating one switch. Workers can perform work without guidance by
observation personnel.
- Excellent waterproof structure
The theodolite body is guarded against a sudden torrential rain and
dirt. The theodolite can be used reliably at work sites under severe
conditions.
