Digital Electronic Surveying Theodolite with 2 Second Accuracy

The SJDJ-J Series laser electronic theodolite has an elegant outline design. The internal structures are waterproof and dust proof with excellent performance. The visible laser line from the telescope is coaxial and coincidence focus with a telescope optical system. The new structures of the collimation laser and laser plummet make the performance of the Theodolite more stable, reliable and easily adjustable. This series of electronic theodolite has wide applications in the Grade III and Grade IV triangle control measurement in national and urban projects, including engineering measurement in railway, highway, bridge, water conservancy, mining projects, etc. It can be also used in various engineering in construction, erection of large equipment and land register and topographic survey and various kinds of engineering measurement. - Rechargeable lithium Battery, stand by time is 80 hours - - The Electronic laser Theodolite adopts the photoelectric incremental angle measuring system - - The instrument integrates laser, mechanical, electronic and computer technologies all in one, providing a variety of functions including angle measurement, display and storage. - It can display horizontal and vertical angles and realize conversion from vertical angle to gradient and compensation of vertical angle. The precision of angle measurement is 2". - Two second angular accuracy. Accurate enough for any construction job Vertical axis compensation - - Tilt sensor provides the highest level of accuracy and be turned on or off depending upon job requirements - - Dual LCD with large characters easy to see; angle readings, eliminate errors and reduce eye fatigue - - Back lit LCD allows work in low light conditions including indoor and extended hours near dawn - - 2 second Laser Theodolite has an operating time of 36 hours w/o the laser. Built-in laser plummet can be interchanged and has a 1.5 mm accuracy - Tri-pod mounting size is 1 3/8 inches
