Product Introduction
The BOIF TDJ2 2-second inverted image theodolite is a precision optical angle-measuring instrument designed for high-accuracy surveying applications including geodetic control networks, construction engineering and industrial installation. Featuring an inverted image telescope system, this instrument provides reliable measurement of horizontal and vertical angles with approximate distance calculation capabilities. Its compact design (310×160×148mm) and 6kg lightweight structure ensure excellent portability for field operations. 13
Technical Specifications
This theodolite achieves ≤±2 seconds horizontal measurement accuracy and ≤±6 seconds vertical accuracy per set, equipped with 360° graduated circle and 1″ minimum optical micrometer reading. The 28x magnification telescope offers 40mm objective lens diameter with 1°30′ field of view, featuring 2m minimum focusing distance. The innovative X-type pendulum compensator effectively minimizes vibration interference, while the air damping structure enhances operational stability. Compatible with Zeiss-style tribrachs, it supports various surveying accessories. 29
Operational Features
The TDJ2 features user-friendly design with color-coded reading reticle for comfortable observation. Its dust-proof telescope incorporates protective glass for the crosshair, ensuring long-term image clarity. The built-in optical plummet provides 3x magnification with 5° field of view and 0.5m-∞ focusing range for precise centering. With 20″/2mm sensitivity plate level and 8′/2mm circular level, the instrument enables rapid leveling. These characteristics make it reliable for demanding measurement tasks. 1319
