【Product Introduction in English】
The DT302L Electronic Theodolite, developed by Suzhou Yiguang Instruments Co., Ltd., is a high-precision angular measurement instrument designed for construction engineering, topographic surveying, road construction, and industrial equipment installation. Featuring an integrated body structure and digital sensing technology, it combines user-friendly interfaces with reliable measurement capabilities.
Equipped with an optoelectronic angle measurement system, the device achieves ±2" accuracy in both horizontal and vertical angles, with a minimum display resolution of 1". The dual-axis automatic compensator effectively corrects measurement deviations caused by minor inclinations, ensuring data reliability. The 6-inch large LCD screen provides dual-sided readouts, maintaining clear visibility even under strong sunlight, while the intuitive button layout enhances operational efficiency in field applications.
With IP54 protection rating and lightweight alloy construction (total weight 4.3kg), the DT302L balances durability and portability. Its rechargeable lithium battery supports up to 30 hours of continuous operation, complemented by USB fast-charging capability for extended field use. Advanced temperature compensation algorithms enable stable performance across a wide operating range from -20℃ to +50℃, adapting to various environmental conditions.
The theodolite features a multi-purpose tribrach compatible with standard tripods, incorporating precisely machined rotation axes for smooth operation. Optional accessories including laser plummets and data storage modules expand its functional versatility. Through dedicated software, measured data can be seamlessly transferred and converted into multiple formats for post-processing and analysis, enhancing workflow efficiency in diverse measurement scenarios.
