Overview for the Sokkia DT240 2" Electronic Digital Theodolite Dual Display
The Sokkia DT240 2 Second Digital Theodolite features superior optics, advanced absolute encoder and automatic compensators for highly accurate angle measurements. With 30X magnification and 2.5-inch telescope resolving power, this optical instrument provides surveyors with crystal clear images of points to ensure that the target is precisely measured.
With 2-second accuracy, the DT240 digital theodolite automatically compensates both vertical and horizontal angles by monitoring the tilt of the instrument in two directions.
The DT 240 has a built-in absolute encoder that utilizes an algorithm to further enhance the reliability of angle measurement. When the instrument is restarted, the azimuth is automatically restored to save time on the job site.
Variety of Display Modes
You can select the angle display unit that best suits you. Horizontal angle is switchable between clockwise and counterclockwise, angle hold and zero-set functions are also provided.
Audible Right-Angle Notification
Once the zero horizontal angle direction is determined, the DT240 survey instrument emits 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.
Simple Interface and Control Panel
This Sokkia theodolite features a simple four-key operation, dual backlit LCD displays and an integrated reticle illuminator that provides clear angle readings and allows construction professionals to work in low light conditions. Field data can also be transferred to external devices via the RS-232C serial port.
Superior Protection and Battery Life
The Sokkia DT240 withstands the harshest jobsite environment with its IP-66 rating for dust and water protection. Powered by four standard AA alkaline batteries, this survey tool operates up to 100 hours and works for two to five weeks without changing batteries depending on usage.
This Sokkia theodolite package comes with a hard carrying case, lens cap, plumb bob, tool pouch, vinyl cover, cleaning cloth, batteries and 1-year manufacturer's warranty.
