【Suzhou Yiguang DT-402L Electronic Theodolite Product Introduction (English Version)】
The Suzhou Yiguang DT-402L Electronic Theodolite is a professional optoelectronic measuring instrument designed for fundamental angular measurement tasks in civil engineering, construction projects, and road surveying. Integrating optical systems with electronic sensing technology through modular design, this device delivers dependable data support for engineering measurement applications.
Equipped with a high-sensitivity dual-axis compensation system, the instrument automatically corrects tilt-induced errors to maintain measurement accuracy in both vertical and horizontal angles. The dual-line LCD display provides real-time readings of horizontal angles, vertical angles, and laser plummet data, ensuring clear visibility under strong ambient light conditions. The visible red laser plummet enhances centering efficiency, working in tandem with the tribrach base for rapid leveling setup.
Functionally, the DT-402L offers essential capabilities including angle measurement and layout positioning. Its rechargeable lithium battery supports 12 hours of continuous operation, complemented by an intelligent power-saving mode to extend working duration. The housing, constructed from engineering-grade reinforced resin, achieves IP55 protection rating through multi-layer sealing technology, suitable for operating temperatures from -20℃ to +50℃. The ergonomic control panel features dedicated function keys and shortcut command combinations, optimizing operational efficiency in challenging field conditions.
This instrument serves various engineering measurement scenarios including building axis alignment, tunnel breakthrough surveys, and slope deformation monitoring. An optional Bluetooth module enables wireless data transmission to smart devices for real-time recording and cloud-based data management. Suzhou Yiguang maintains a nationwide service network to provide periodic calibration and technical support throughout the product lifecycle.
