Product Overview (English)
The Suzhou FOIF DT302L Electronic Theodolite is a high-precision engineering instrument designed for applications such as railway, highway, bridge, hydropower, and mining construction. Its laser plummet feature utilizes a semiconductor laser emitter (635nm wavelength) for efficient centering, with the laser beam coaxial and parfocal to the telescope’s line of sight (deviation ≤5″) and a daytime effective range of 200m. Equipped with an absolute encoding angle measurement system (1″ minimum reading, 2″ accuracy), a 30× magnification erect-image telescope (1°30′ field of view, 1.3m shortest sighting distance), it ensures reliable performance in complex environments. The user-friendly interface includes a large Chinese LCD screen and a multi-angle averaging function to enhance data precision. Laser plummet and pointing operations are panel-controlled for convenience and safety. With a compact design (153×175×328mm, 4.0kg) and support for Ni-MH/alkaline batteries (up to 80 hours of operation), it is ideal for extended fieldwork.
技術特點（中文）
DT302L集成電子補償器（補償范圍±3′），可自動修正傾斜誤差，提升測量穩定性。激光對點模塊采用低功耗設計，僅需2節AA電池供電，光斑清晰可見。雙面顯示屏支持多角度數據讀取，內置RS-232C接口便于外接手簿數據傳輸。儀器適用于地籍測量、地形測繪及大型設備安裝校準，尤其適合需快速對中的施工場景。望遠鏡繞軸設計支持盤左/盤右測量，兼顧傳統經緯儀功能與激光導向優勢。
Technical Highlights (English)
The DT302L integrates an electronic compensator (±3′ range) for automatic tilt correction, ensuring measurement stability. The laser plummet module features low-power consumption (2×AA batteries) and a bright visible spot. Dual-sided displays facilitate multi-angle data reading, while the RS-232C interface enables external data logging. Ideal for cadastral surveys, topographic mapping, and large equipment alignment, its telescope’s rotating axis design supports face-left/face-right measurements, combining traditional theodolite functions with laser guidance efficiency.
