Exclusive Features for the Laser Models:

200m (660ft) - long-range laser pointer

0.4mm@10m - ultra-small beam spot

Sokkia's Digital Theodolites allow you to survey with ease using the absolute encoder's new algorithm that operates with remarkably reduced power consumption. When the instrument is restarted, the azimuth is automatically restored to save time on the job site. A large LCD screen provides clear angle reading under all conditions, and thanks to simple 4-key operation, no training is required

Variety of display modes

• You can select the angle display unit that best suits you. Horizontal angle is switchable between clockwise and counterclockwise, 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 utilize RAB (RAndom Bi-directional) code and digital sampling technology, further enhance the reliability of angle measurement. DT240 guarantees 2" accuracy 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. Powered by 2 standard LR14/C alkaline batteries, the DT240 will operate for 75 hours.

One-key Start

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

Easy-to-read, easy-to-use control panels

• A large LCD screen provides clear angle readings under all conditions, and thanks to simple 4-key operation no training is required. The DT240 has control panels on both faces for added convenience.

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 degrees of 90 degrees and stops beeping when it comes within +/-1 degree.

Superior IP66 protection

• Complying with the tough IP66 standard for resistance to dust and water, both models offer superior dependability even under harsh environmental conditions.
