Introduction to DE2A-L Laser Electronic Theodolite
The DE2A-L Laser Electronic Theodolite, developed by Changzhou Dadi, is a high-precision engineering measurement instrument featuring a full Chinese display interface and user-friendly design. It is widely used in construction, roadworks, hydraulic engineering, and equipment installation. Equipped with dual laser plummet (up and down), it simplifies centering operations, while the data retention function ensures seamless measurement continuity after power cycles. The robust metal housing and steel-axis structure, combined with imported lubricants, enhance durability and stability.121
Key Technical Features
The DE2A-L utilizes an encoded angle measurement system, achieving digital and intelligent angle readings with an accuracy of 2 seconds. It supports multiple angle units (360°, 400gon, 6400mil) and integrates a 635nm laser plummet with a 200m effective range (5mm/100m spot diameter). The waterproof telescope offers a 47mm objective lens aperture, 3.75″ resolution, and 1m minimum sighting distance. Powered by rechargeable Ni-MH batteries, it operates continuously for 10 hours.312
Functional Advantages
With optional optical and laser plummets, the DE2A-L adapts to diverse fieldwork requirements. Its coaxial locking and fine-tuning spirals streamline operation, while the dual LCD panels and standardized key layout improve usability. The vertical laser projection function expands applications as a laser plummet. Compact dimensions (180×166×355mm) and 6.5kg weight ensure portability.824
