Topcon DT-200 Series Digital Theodolite

Topcon DT-200 Series Digital Theodolite

Model: SL-SE-006

The Topcon DT-200 series integrates the same high-quality advanced absolute circle reading technology found in Topcon's high-performance total station products for more accurate field calculations; and they continue to deliver the highest quality optics and electronics you expect to find in Topcon theodolites.

Topcon DT-200 Series Features:
. Long Battery Life
. Waterproof and Dustproof Digital Theodolites

Available in three affordable models delivering 5?, 7?, or 9? angle accuracy, there is a DT-200 theodolite perfect for any job. Like the DT-100 series, the DT-200 series weathers any wet or dust conditions in the field, allowing for a more productive day during inclement weather. All models are also compact and lightweight for easy portability; and their simple operation provides precise measurement in a functional, hassle-free package.
. Longer battery powering duration

Longer battery powering durations using alkaline batteries. Continuous angle measurement for 150 hours. 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)
