Overview for the Topcon DT-207L 7" Waterproof Digital Theodolite with Laser Pointer
The Topcon DT-207L 7 Second Digital Theodolite has a built-in laser pointer with pin-point accuracy for precise layout and alignment applications. This optical instrument also has an advanced absolute encoder for accurate angle calculations and high quality telescope with 30x magnification and three feet minimum focus distance for viewing high quality target images even in tight areas.
Visible Laser Beam
Outside in daylight, the integrated laser pointer can be seen up to 165 feet away for quick aiming and as a guide during layout. The bright red laser beam also allows construction professionals to accurately place bolts at regular intervals on a line, set an angle or sight in footers and tilt-up walls.
With built-in absolute encoder, surveyors can take measurements as soon as the theodolite is turned on. 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.
The DT207L also includes a detachable tribrach with bubble vial and a built-in optical plummet for precise positioning and leveling of the instrument on the jobsite.
Dual Screens and Keypad
Two large LCD displays and five-button panel provide you with a simple interface to quickly take horizontal and vertical angle measurements. This Topcon digital theodolite also features a reticle illuminator that allows you to work in low light conditions.
With an IP-66 rating for dust and water protection, the DT 207L 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 150 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.
