Product Overview
The J2-2 Optical Theodolite is a high-precision surveying instrument designed for engineering, industrial, and geodetic applications. Featuring an erect-image telescope with bright and clear imaging, it combines digital reading systems for user-friendly operation and reliable data output. The vertical circle index automatically compensates to zero, enhancing efficiency in vertical angle measurement. Its integrated widened支架 supports compatibility with various infrared rangefinders, extending functional versatility.19
Key Features
With a horizontal direction accuracy of ±2″ and vertical angle accuracy of ±6″ per measurement set, the J2-2 ensures high-precision results. The 30x magnification telescope and 2m minimum focusing distance enable detailed close-range observations. The semi-kinematic轴系 design offers wear resistance and thermal stability. In its laser-enhanced variant (e.g., J2-JDE), a semiconductor laser emitter projects a visible beam for alignment tasks in shipbuilding, tunnel construction, and structural deformation monitoring.712
Applications
This instrument is widely used in triangulation, traverse surveys, and精密工程 control. It facilitates centerline marking and verticality checks in construction,定向测量 in mining, and displacement monitoring for bridges/dams. Compatible with modular accessories, it adapts to天文观测 and mechanical alignment scenarios. The laser version’s dual-curved eyepiece supports zenith observations, doubling as a plummet telescope.320
Design Advantages
The three-claw base ensures stability, while the magnetic-damped compensator with dual safeguards minimizes vibration damage. Laser models operate on two AA batteries for extended field use. Weighing仅6kg, it balances portability with ruggedness, ideal for demanding environments.425
