TDJ6E

Description

The TDJ6E optical theodolite can be used for various professional surveying in the construction and many other fields. It adopts an X-long pendulum compensator, which can automatically compensate the index error of vertical circle, and features good resistance to high-frequency vibration. Due to the optical micrometer, this precision optical instrument can directly read the vertical angle and horizontal angle to a high accuracy of 1″ or 1cc. The telescope of the optical theodolite can present either erect images. The unique design of air damping structure makes stable and reliable performance of the instrument possible. The color field makes the circle easy to read with accuracy.

Manufactured according to the GB/T3161-2003 national standard, the optical theodolite can be used for third and fourth class national triangulation, precise traverse survey, setting out survey, and the installation of precision machinery. In most cases, it is usually placed on a tripod in the field, and can be commonly found in the hydrological investigation, geological exploration, road laying, water course, bridge, water control projects, urban construction, etc.
