Overview for the Sokkia DT940 9″ Electronic Digital Theodolite Single Display
The Sokkia DT940 Digital Theodolite with 9-second accuracy enables surveyors to precisely measure angles for general construction application. Featuring advanced absolute encoder, tilt sensors, 26x magnification and 3-inch telescope resolving power, this optical instrument offers exceptional battery life and crystal clear images of points.
With the built-in absolute encoder, you can start taking reliable angle measurements as soon as you turn on the power. By using advanced algorithm and digital sampling technology, the azimuth is automatically restored when the instrument is shut down or restarted to save time on the job site.
Choice 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.
The DT940 survey instrument produces audible tones for each of the four right-angle directions once the zero horizontal angle direction is determined. It sounds two different tones within ±15 degrees of 90 degrees and stops beeping when it comes within ±1 degree.
Featuring a single backlit LCD display and four-key operation, this Sokkia theodolite provides construction professionals with clear angle readings and short learning curve.
Ultra-Long Working Hours
The Sokkia DT940 boasts an IP-66 rating for protection to dust and water resistance. It also uses four AA alkaline batteries for up to 170 hours of operating time and works for two to five weeks without changing batteries depending on usage.
