The World's Longest Operating Time
• SOKKIA's innovative technology achieves the world's longest operating time* – 220 hours with the 7"-DT620 model.
• The DT520A operates up to 200 hours - the longest among 5" models*.
• At 7 hours/day, the DT620/DT520A can operate for more than 31/28 respective days without changing batteries.
Advanced Angle Measurement System
• The DT series theodolites are equipped with market-proven absolute encoders. Advanced coding and digital processing technologies provide long-term reliability in any work-site conditions.
• 2"-DT220 incorporates IACS (Independent Angle Calibration System) to further enhance measurement reliability.
• 5"-DT520A and 7"-DT620 employ newly developed IACS-SD* technology that provides high accuracy with the power-efficient single-detection system.
Quick, User-friendly Operation
• Start measurement as soon as you turn on the power without the need for 0-indexing.
• Easy-to-read LCD display has 20% larger digits than former models.
• The MENU key facilitates all instrument settings including angle units, resolutions, measurement modes, tilt compensation and so on.
Dual-axis Compensation (DT220 • DT520)
• DT220/DT520 models automatically compensate both Vertical and Horizontal angles by monitoring instrument tilt in X &Y directions.
Right-angle Beeps
• Beeps at each of the four right-angle directions to assist squaring.
Industry's Highest* Dust- and Water-Protection
• All models comply with the rigorous IP66 standard, offering superior protection against powder-type dust and sudden showers.
