LT402L雙軸激光電子經緯儀是一款面向工程測繪領域的精密測量儀器，采用創新光學系統與電子傳感技術相結合的設計方案，在建筑施工、道路勘測、水利工程等領域展現穩定可靠的測量性能。設備搭載上下雙激光發射系統，可實現水平方向與垂直方向同步激光指示，配合高精度角度傳感器，確保測量過程中基準線的快速建立與精準定位。
該設備配備智能化電子測角系統，支持水平角與垂直角雙軸同步測量，最小顯示精度可達1"，測角范圍覆蓋0°至360°全方位角度。激光對中器采用可見紅光設計，在15-100米范圍內保持清晰光斑顯示，便于現場施工人員快速識別定位點。儀器搭載抗震補償系統，有效緩解外界震動對測量精度的影響，保證在-10℃至+50℃環境溫度下維持±2"的測角精度。
人性化設計方面，LT402L配置雙面6鍵防塵按鍵面板與高清液晶顯示屏，支持正像望遠鏡系統，確保操作者在復雜工況下仍可清晰讀取測量數據。儀器內置可充電鋰電池組，滿電狀態下可持續工作30小時，配備Type-C通用充電接口滿足現場快速補給需求。整機采用壓鑄鋁結構框架，通過多重防塵防水處理，在惡劣工地環境中仍能保持穩定工作狀態。
LT402L Dual-axis Laser Electronic Theodolite is a precision measurement instrument designed for engineering surveying applications. Integrating advanced optical systems with electronic sensing technology, it delivers reliable performance in construction projects, road surveying, and hydraulic engineering. The dual-laser alignment system enables simultaneous horizontal and vertical laser indication, working in tandem with high-precision angle sensors to ensure rapid baseline establishment and accurate positioning during measurement operations.
Equipped with an intelligent electronic angle measurement system, the device supports dual-axis synchronous measurement of horizontal and vertical angles, achieving 1" display resolution with full 0°-360° angular coverage. The visible red laser plummet maintains clear spot visibility within 15-100 meters range, facilitating quick identification of reference points at construction sites. Its vibration compensation mechanism effectively minimizes measurement errors caused by environmental disturbances, maintaining ±2" angle measurement accuracy across -10℃ to +50℃ temperature ranges.
User-oriented features include a dust-proof 6-button control panel and high-contrast LCD display, complemented by an erect-image telescope system that ensures legible data reading in complex working conditions. The built-in rechargeable lithium battery provides up to 30 hours of continuous operation, supported by Type-C universal charging interface for convenient power replenishment. Constructed with die-cast aluminum framework and multi-layer dust/water resistance treatment, the instrument maintains operational stability even in challenging field environments.
