Sokkia DT-540L, DT-740L, DT-940L Digital Theodolite

Quality, Performance, and Affordability that Ensure Maximum Profitability
SuperiorPerformance and Durability
All models feature superior optics, mechanics, advanced absolute encoder systems, proven tilt compensators, and the industry's highest IP66 protection grade.
Power-Saving Technology Saves Battery Costs
Four AA alkaline batteries provide extra-long operating time from 100 to 170 hours, saving costs for replacement batteries. The DT Series instruments operate for two to five weeks without changing batteries*.
* When used for seven hours a day, five days a week, excluding the use of laser pointers.
Laser Pointer to Increase Construction Work Efficiency (Laser models) (The laser models incorporate built-in coaxial laser pointers that maximize construction work efficiency).

The applications include:
  • Layout (Setting-Out)
  • Horizontal/Vertical Alignment
  • Leveling
  • Grading
  • Squaring
