TDJ2Z Autocollimation Theodolite

1. With vertical index automatic compensation function, the TDJ2Z autocollimation theodolite offers good capability in anti-high frequency vibration.
2. Colorful reading ensures convenience and clarity.
3. The horizontal and vertical angle measured by an optical micrometer can be accurate to 1"or 1cc.
4. The telescope supports both erect and inverted images, and is compatible with universal tribrach.
5. Due to our unique design of air damping structure, the instrument has stable and reliable performance.

The autocollimation theodolite is widely used in national trigonometric survey, precision traverse survey, layout survey, as well as huge engine installation and computation fields.

  • TDJ2E Optical Theodolite The X-long pendulum compensator of our optical theodolite can automatically compensate the index error of vertical circle, and has good resistance to high-frequency vibration.
    The color field makes the circle easy to read and ensures clear readings.
    Due to the optical micrometer, the vertical angle and horizontal angle can be directly read to a high accuracy of 1" or 1cc.
  • 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.
