Sokkia DT940L 9" Electronic Laser Digital Theodolite Single Display
Sokkia's   Digital Theodolites ensure maximum job efficiency at unmatched   performance levels. Sokkia's new theodolites feature superior optics,   advanced absolute encoder systems, and proven automatic compensators. In   addition to these essential technologies, the Sokkia DTx40 series   boasts the industry's highest IP66 dust and water protection capability   to withstand the harshest jobsite environments.
  
  Common Features for All Models:
  • 2.5" - unsurpassed telescope resolving power* 
       
  *except for the DT940L
 
  
  • IP66 - industry's highest dust/water protection rating
  
  • Absolute encoders• Up to 170 hours of operating time
  
  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.
  
  Dual-axis compensator
  The   DT240 automatically compensates 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 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.
  
  RS-232C port
  Measurement data can be output to external devices via the RS-232C data port.
  
  The   DT240 Includes: Two R14/C alkaline batteries, lens cap, lens hood,   plumb bob, tool kit, operator's manual, carrying case, and shoulder   strap.
