Theodolite Digital Sokkia DT-540
The Sokkia DT-540 Digital Theodolite features a long-range laser pointer that makes sighting exact points easier and facilitating alignment, layout, leveling, grading and squaring application. With 5-second accuracy, this optical instrument delivers crystal clear images of points with its telescope’s 30X magnification and 2.5-inch resolving power. It also features a built-in absolute encoder and automatic axis compensation for reduced power consumption and correcting tilt errors.Laser with Ultra-Small Beam Spot
Under indoor or underground conditions, the DT 540L’s laser pointer reaches 660 feet. The ultra-narrow beam precisely measures through walls, corners, fence openings and tree branches. This visible laser is coaxial, making outdoor aiming quick while providing construction professionals with direction during layout.
Dual-Axis Compensator
The DT540L digital theodolite automatically compensates both vertical and horizontal angles by monitoring the tilt of the instrument in two directions.
Enhanced Reliability with Absolute Encoders
Integrated absolute encoder utilizes advanced algorithm and digital sampling technology that allows surveyors to start taking measurements as soon as the theodolite is turned on. This technology remarkably reduces power consumption by restoring the azimuth after the instrument’s power is cut off.
Different Display Modes
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.
Right-Angle Notification
Once the zero horizontal angle direction is determined, the DT540L 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.
Easy to Use Control Panel
This Sokkia theodolite features a simple 4-key operation, dual and an integrated reticle illuminator that provides clear angle readings and allows construction professionals to work under all lighting conditions. Field data can also be transferred to external devices via the RS-232C serial port.
Reliable with Long Working Hours
Complying with the tough IP-66 standard for resistance to dust and water, the Sokkia DT540L offers superior dependability under harsh environments. This survey tool is powered by four standard AA alkaline batteries that operates up to 140 hours and works for two to five weeks without changing batteries depending on usage.
