【English Introduction】
The TDJ2 2-second optical theodolite is a precision surveying instrument designed for high-accuracy geodetic measurements, ideal for topographic mapping, engineering layout, and geological exploration. Equipped with an advanced inverted-image optical system, it delivers high-contrast target imaging capabilities that significantly enhance observation efficiency in challenging environments. With angular measurement accuracy of 2 seconds, both horizontal and vertical angle measurement errors are maintained within rigorous industry parameters, ensuring reliable performance for precision engineering applications.
Featuring a lightweight yet durable aluminum alloy frame, the instrument integrates multi-layer coated objective lenses and anti-fog optical components. Its temperature-resistant design guarantees stable operation across extreme conditions from -20℃ to +50℃. The user-centric interface includes dual-axis fine motion screws and a laser plummet, enabling single-operator leveling adjustments within 30 seconds. The detachable tribrach system supports multiple terrain-adaptive tripod interfaces, allowing rapid deployment on uneven ground surfaces.
This theodolite streamlines workflow through Bluetooth-enabled data transmission to mobile devices, compatible with major CAD and GIS platforms for seamless field-to-office data integration. The shockproof carrying case and portable power kit ensure equipment protection during extended field operations. Suitable for civil engineering, mine monitoring, road construction, and hydraulic projects, it provides survey professionals with an optimized combination of optical performance and operational efficiency. The modular design allows easy maintenance and accessory upgrades, extending equipment service life across diverse project cycles.
