By telescope, horizontal circle, vertical dial, spirit level, base and other components. When ordinary theodolite, the theodolite tripod, with a plumb bob or optical plummet instrument centering on the floor of the station Su optical theodolite, theodolite instrument with a vial given level, with a telescope aimed at measuring the goal, with the level of degree dial plate and the vertical angle measuring horizontal and vertical. Divided by accuracy and precision theodolite theodolite general; by reading equipment can be divided into optical theodolite theodolite and cursors; retest divided by shafting structure and direction theodolite theodolite.
