Perhatian!
Spesifikasi Theodolite Topcon DT 209
Deskripsi :
- 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.
JIS C 0920 protection class IP66 (Dustproof and waterproof types)
