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.
