Theodolites. The Topcon DT-200 Series.

Topcon DT-200 Series Theodolites.

The DT-200’s design is based on the DT-100, with the following technical improvements;

Absolute angle encoder system; removes the need to move horizontal and vertical angle scales when turning on.
All models fully waterproof (IP66 !)
Operating time greatly improved, minimal 140 hours
1" (0.2mgon) minimum reading on the 5" accuracy model.

The Series consists of 3 basic models DT-205, DT-207 and DT-209 with 5"(1.5mgon), 7"(2.1mgon) and 9"(3mgon) angle accuracies respectively.

For the construction site and quick easy instrument set-up, the DT-209P is available with quick-centering tribrach.

Laser Theodolites

Each of the new models is available as a Laser theodolite version. DT-205L, DT-207L and DT-209L have the same specifications as the basic models with the addition of a visible red laser beam coaxial with the optics of the telescope.

This Class 2 laser is focused through the telescope ensuring a clearly defined and visible spot at a distance of upto 50 meters.

These laser theodolites are the ideal tools for many construction site alignment tasks and setting out jobs.
