The DT300 Series Electronic Theodolite is a high-precision optical measurement instrument series engineered for construction surveying applications, featuring two core models: DT302 Basic Edition and DT305 Enhanced Edition. With integrated compact structure and digital measurement technology, this product line delivers reliable performance in azimuth measurement, horizontal angle measurement, and vertical angle measurement across diverse scenarios including building construction, topographic mapping, and road engineering.
The DT302 model is equipped with a 4.3-inch high-brightness LCD display featuring multi-level backlight adjustment, ensuring clear data visibility under strong sunlight. Its angle measurement system incorporates high-sensitivity photoelectric encoders, achieving ±2" accuracy in horizontal measurement and ±5" in vertical measurement. The dual-axis compensation system effectively minimizes measurement deviations caused by environmental vibrations. Powered by removable lithium battery packs, it sustains 12-hour continuous operation and enables rapid data export via USB-C interface.
The upgraded DT305 model introduces wireless connectivity with Bluetooth 5.0 technology, allowing real-time data transmission to mobile devices through dedicated APP for 3D coordinate visualization and point marking. Its enhanced laser centering device improves optical centering accuracy to 0.8mm/1.5m, particularly suitable for confined space positioning. With IP54 protection rating, both models maintain operational stability in drizzling or dusty conditions. The ergonomic keyboard design with intuitive menu navigation enables swift mode switching between single measurement, continuous measurement, and data review functions.
Constructed with lightweight metal frame (total weight under 2.8kg), the series features rotatable eyepiece and adjustable tripod adaptor, significantly improving workflow efficiency in challenging terrains. These instruments serve as dependable angle measurement solutions for construction layout, hydraulic facility monitoring, mine tunnel surveying, and other professional engineering applications, delivering consistent performance through advanced optical-electronic integration.
