Product Overview
The Nanjing 1002 Factory J6E Direct Image Optical Theodolite is a precision optical instrument designed for engineering surveys and topographic mapping. Featuring an erect-image telescope system with clear visualization, it is suitable for low-order control surveys, mine surveys, and construction measurements. With an operational temperature range of -25℃ to +45℃, the instrument maintains stable performance in harsh environments. Key features include an optical scale reading system, anti-torsion spring mechanism, and semi-kinematic vertical axis structure. 1915
Technical Specifications
Equipped with a 29x magnification telescope (40mm objective aperture, 1°20′ field of view), the J6E offers focusing range from 2m to infinity. Horizontal and vertical circles feature 1′ graduations (estimable to 6″), supported by 73x/74x microscope amplification. The built-in optical plummet (1.1x magnification, 4° FOV) and forced-centering ball track bearing system ensure operational stability. Weighing 4.2kg net, its compact design suits field operations. The instrument includes dual-stadia lines for distance measurement applications. 41222
Applications
Ideal for topographic mapping, railway construction, and mine surveying, the instrument delivers ±6″/set horizontal accuracy and ±9″ zenith angle accuracy. The dual-line reticle system accommodates various targeting needs while stadia lines facilitate distance measurement. Pre-delivery environmental simulation tests and anti-fog treatment guarantee long-term reliability for cadastral surveys and engineering layout tasks. 61426
