The 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.
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.
