Product Introduction
The FOIF J2-2 Optical Theodolite is a professional-grade angle measuring instrument manufactured by Suzhou FOIF Instrument Co., Ltd. Featuring erect-image optics and robust mechanical construction, this device delivers reliable performance for various surveying applications including construction layout and industrial alignment. The instrument has gained recognition in over 100 countries for its consistent quality.318
Key Features
This theodolite incorporates a 30x magnification telescope with 40mm objective lens diameter, providing bright and clear imaging even in challenging lighting conditions. The innovative moving optical wedge micrometer system enables precise angle measurements, while the pendulum-type automatic vertical index compensator ensures accuracy during tilt measurements. The lightweight (6kg) yet durable design includes dust/water resistance for field durability.1324
Typical Applications
Ideal for civil engineering projects requiring high-angular accuracy, the J2-2 performs exceptionally in shipbuilding alignment, dam deformation monitoring, and precision machinery installation. The laser-enhanced version (J2-JDE) projects a visible 635nm laser beam co-axial with telescope line of sight, particularly useful for night operations and confined space measurements. Standard accessories include tribrach base and dual-purpose optical/plumb bob centering devices.1122
