The laser theodolite is a combination of advanced digital theodolite and modern semiconductor laser, and is a professional measuring instrument that can project a visible laser reference line for accurate measurement in construction and other fields. The display interface with big screen and the Operation panel with big buttons allow for easy Operation. It also has a RS-232C serial communication interface, and can store 500 points of measurement data. When coupled with the diagonal eyepiece, this electronic theodolite can be used instead of the plummet. Through the use of this instrument, both the horizontal and vertical angle can be read to a high accuracy of 1".
