Sokkia Digital Theodolites

Highlights

• Dramatically, decreased operating time.
• The new algorithm which operates the absolute encoders has remarkably reduced power consumption.
• A large LCD screen provides clear angle reading under all conditions, and thanks to simple 4-key operation, no training is required.
• Offers superior dependability even under harsh environmental conditions.

Variety of display modes

You can select the angle display unit that bests suits you. Horizontal angle is switchable between clockwise and counter-clockwise, and angle Hold and 0-set functions are also provided. Vertical angle can be set to Zenith=0, Horizontal=0, Horizontal=0±, or % of slope.

Enhanced reliability with absolute encoders

Sokkia's market proven advanced absolute encoders, which utilise RAB (RAndom BI-directional) code and digital sampling technology, further enhance the reliability of angle measurement. DT210 guarantees 2" accuracy, DT510/510A ensure 5" accuracy and DT610-7" for both horizontal and vertical angles.

Ultra-long working hours

With Sokkia's new algorithm in operating absolute encoders, power consumption has been dramatically reduced. Power by 2 standard LR14/C alkaline batteries, the DT210 and DT510 will operate for 75 hours, while the DT510A and DT610 will work for and astonishing 110 hours

One-key start

you can start taking measurements as soon as you turn ion the power, thanks to the absolute encoders. Moreover, azimuth is kept when restarting the instruments after turning off the power.

Dual-axis compensator

The DT210/DT510 automatically compensate both Vertical and Horizontal angles by monitoring the tilt of the instrument in X&Y two directions.

Audible right-angle notification

Once the zero (0) horizontal angle direction is determined, all models emit audible tones for each of the four right-angle directions. Specifically, it sounds two different tones within ±15° of 90° and stops beeping when it comes within ±1°.
