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.
TDJ6E Optical Theodolite
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.

AL0732/AL1032 Automatic Level
The AL0732 and AL1032 automatic level can realize the precision measurement of national third class leveling and can also meet customers' different measurement requirements, with a height accuracy of 1.5~2.5mm and a leveling accuracy of ±0.3". It is composed of a high-precision compensator, with a high compensation accuracy of ±0.3". In addition, the compensator adopts the cross hang spring and air damper, and works together with a machine used for compensating temperature at the same time.
AL100 Automatic Level
With the stylish and portable design, the automatic level is most suitable for field surveying work. It is composed of a high-precision compensator, with a high compensation accuracy of ±0.3". In addition, the compensator adopts the cross hang spring and air damper, and works together with a machine used for compensating temperature at the same time. Our automatic level also adopts friction motion and infinite micro-motion mechanism for accurate leveling.
