Overview for the Topcon DT-209 Waterproof and Dustproof Digital Theodolites

The Topcon DT-209 9 Second Digital Theodolite accurately calculates vertical and horizontal angles. Featuring an advanced absolute encoder and high quality telescope with 26x magnification and 3-inch resolving power, this optical instrument produces reliable angle measurements and exceptional viewing quality of the target.

Absolute Encoder

Surveyors can take measurements as soon as the theodolite is turned on with the built-in absolute encoder. This technology uses advanced algorithm to restore the azimuth after the instrument’s power is cut off, improving reliability of angle measurements and reducing power consumption.

Fast Set-Up

The DT209 also includes a fixed tribrach with bubble vial and a built-in optical plummet for precise positioning and leveling of the instrument on the jobsite.

Single Display and Functional Keys

A large LCD display and simple five-button panel provide you with a simple interface to quickly take horizontal and vertical angle measurements.

Ultimate in Continuous Operation

With an IP-66 rating for dust and water protection, the DT 209 digital theodolite promotes productive surveying even in harsh weather. Its telescope is also constructed to prevent moisture and eliminate lens fogging. Compact and lightweight, this survey tool offers up to 170 hours of continuous measurement in angle mode using four standard AA alkaline batteries.

This Topcon theodolite package comes with a hard carrying case, plumb bob, tool kit, waterproof protective cover, lint-free lens cloth, batteries and 5-year manufacturer's warranty.
