DJD2-C/E Series Electronic Theodolite Introduction
The DJD2-C/E series electronic theodolite is an intelligent measurement instrument developed for engineering surveying and topographic mapping, integrating optical measurement technology with electronic sensing systems. Suitable for civil engineering, geological exploration, construction projects and other professional fields, this product adopts modular design principles to optimize measurement functions while maintaining instrument stability.
Equipped with a self-developed digital angle measurement system, the device utilizes high-sensitivity sensors to capture horizontal and vertical angles with 0.5" resolution, meeting precision requirements for standard engineering surveys. The dual-axis compensation system automatically corrects instrument tilt errors, ensuring data reliability in complex terrain conditions. Distance measurement function supports single-prism mode with maximum range up to 800 meters, while the integrated laser plummet improves setup efficiency by approximately 30%.
Constructed with aerospace-grade aluminum alloy frame and sealed dust-proof structure, the instrument achieves IP55 protection rating and maintains stable operation within -20℃ to +50℃ temperature range. The 6-inch LCD display features multi-level brightness adjustment for clear visibility in strong sunlight. Built-in rechargeable lithium battery supports 12 hours continuous operation, with USB-C fast charging interface enabling full recharge within 1.5 hours.
Ergonomic design includes anti-misoperation key layout and intelligent voice prompts to minimize operational errors. Expandable SD card storage records over 50,000 measurement datasets compatible with mainstream mapping software formats. The included portable case made of EVA shock-absorbent material provides reliable protection during transportation.
