J6光學經緯儀采用高精度玻璃度盤測角系統，配備30倍率廣角目鏡，可實現水平角與垂直角的高效觀測。全封閉式金屬機身設計有效隔絕粉塵與濕氣，確保設備在-20℃至+50℃環境下穩定運行。其獨特的雙軸補償系統能自動修正微小偏差，特別適用于橋梁施工、礦山巷道等復雜場景的定位測量。儀器配備可拆卸式三腳架連接座，便于現場快速架設。
J6E型在J6基礎架構上進行了輕量化改進，整機重量降低18%至4.2kg，同時保持IP54防護等級。新增激光對點裝置使儀器架設效率提升40%，獨創的視距乘常數自動修正功能，將距離測量誤差控制在1/3000以內。該型號特別適合水利工程監測、城市管網布設等需要頻繁轉點的作業環境，其模塊化設計使日常維護更加便捷。
南昌系列經緯儀采用多鏡組復合光學系統，成像清晰度達到3.5角秒分辨率。儀器轉軸系統經過特殊硬化處理，在連續工作狀態下仍能保持轉動順滑。人性化的操作界面配備雙向微動螺旋，支持單手精確調焦。該系列產品廣泛應用于高校教學示范、古建筑測繪等對操作便捷性要求較高的領域，其可靠的機械結構設計確保儀器在長期使用中保持測量精度。
Nanjing 1002 Factory Optical Instrument Introduction
As a veteran manufacturer in China s optical instrument industry, Nanjing 1002 Factory has dedicated itself to precision optical device development for decades. The J6, J6E theodolites and Nanchang series instruments have gained recognition in engineering surveying and geological exploration through their reliable performance.
The J6 Optical Theodolite features a high-precision glass circle measurement system with 30x wide-angle eyepieces, enabling efficient horizontal and vertical angle observation. The fully enclosed metal housing effectively resists dust and moisture, maintaining stable operation from -20℃ to +50℃. Its dual-axis compensation system automatically corrects minor deviations, making it particularly suitable for positioning tasks in bridge construction and mine tunnel projects. The detachable tripod adapter allows rapid field setup.
The upgraded J6E model achieves 18% weight reduction (4.2kg total) while maintaining IP54 protection. The integrated laser plummet improves setup efficiency by 40%, with automatic stadia constant correction ensuring distance measurement accuracy within 1/3000. Ideal for hydraulic monitoring and urban pipeline projects requiring frequent relocation, its modular design simplifies maintenance.
Nanchang Series Theodolites employ multi-lens optical systems delivering 3.5 arc-second resolution. Specially hardened axis mechanisms ensure smooth rotation during prolonged operation. The ergonomic interface with dual fine-motion screws enables single-handed focusing. Widely adopted in academic training and heritage architecture documentation, these instruments maintain measurement precision through robust mechanical construction. Non-reflective surface treatment minimizes light interference in outdoor environments.
