Product profile  :  TD-1EA Optical Theodolite

The TD-1EA optical theodolite can be used for various professional surveying in the construction and many other fields. As the technical specifications of this precision optical instrument are in full compliance with the GB/T3161-2003 national standard, it can be used for third and fourth class national triangulation, precise traverse survey, setting out survey, and precision machinery installation.
With the unique design of air damping structure, the instrument can work stably and reliably during the whole measurement process. The color field also makes the circle easy to read and ensures clear readings. Placed on a universal tripod, our optical theodolite has found applications in the hydrological investigation, geological exploration, road laying, water course, bridge, water control projects, urban construction, etc.
1. Due to the optical micrometer, the vertical angle and horizontal angle can be directly read to a high accuracy of 1" or 1cc.
2. The telescope of the optical theodolite can form erect and reverse images.
3. With good resistance to high-frequency vibration, the X-long pendulum compensator of our optical theodolite can also automatically compensate the index error of vertical circle.
