Overview for the Topcon DT-205L 5" Waterproof Digital Theodolites with Laser Pointer
The Topcon DT-205L 5 Second Digital Theodolite with Laser Pointer allows surveyors to perform highly accurate alignment jobs. This optical instrument features 30x magnification and 2.5-inch telescope resolving power for exceptional image quality of target points. Built-in dual backlit displays and a tilt sensor with angle correction also ensure accurate angle measurements.
Integrated red laser beam can be used anywhere and seen clearly in direct sunlight up to 165 feet away. This allows construction professionals to accurately place bolts at regular intervals on a line, set an angle or sight in footers and tilt-up walls. It also promotes quick aiming and provides direction to the rod-man during layout.
Automatic Angle Correction
With dual-axis compensation, the DT205L automatically monitors and corrects shifting of both vertical and horizontal angles. It also has a detachable tribrach with bubble vial and a built-in optical plummet for easy set-up and precise leveling.
Absolute encoder uses advanced algorithm to resume the measurement point after the instrument is turned off. This technology saves time on the job site, reduces power consumption and improves reliability of angle measurements.
The two high contrast LCDs, five-button keypad and reticle illuminator enable surveyors to see clear angle readings and operate the DT 205L inside buildings, tunnels or mines. With the RS-232C serial port, you can also transfer field data to a computer easily.
Impressive Battery Life
With an IP-66 rating, this digital theodolite resists any moisture or dust conditions in the field, allowing for a more productive surveying during inclement weather. It is compact and lightweight for easy portability and works up to 140 hours 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.
