Topcon DT-200 Series Digital Theodolite.
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.
