【Product Introduction in English】

The XX Series Total Station/GPS Centering Rod Bubble Calibration Module is a professional auxiliary tool developed for high-precision measurement operations. Featuring a monocoque metal construction, the product utilizes lightweight alloy materials that ensure structural integrity while maintaining optimal portability. The core component integrates a 32mm diameter high-visibility leveling bubble with dual-sided anti-glare treatment on the observation window, delivering clear visual positioning even under intense sunlight.

Specifically engineered for 25mm diameter centering rods, this system incorporates a proprietary quick-release mounting mechanism. The triple-axis fine adjustment knobs allow ±5° calibration range for precise alignment. The anodized aluminum housing creates a durable protective barrier against abrasive particles and moisture exposure commonly encountered in construction environments. Internally, the bubble assembly employs precision ball-bearing mechanisms combined with vibration-dampening pads to maintain calibration accuracy during dynamic operating conditions.

The Leica-compatible centering rod adapter is manufactured through CNC precision machining, achieving interface tolerances within 0.02mm. Modular architecture enables swift disassembly for maintenance, allowing field technicians to perform routine cleaning and calibration using standard tools. The integrated 360° rotating orientation ring facilitates multidirectional alignment during complex measurement tasks.

Ideal for topographic surveying, engineering layout, and road construction applications, this system excels in scenarios requiring frequent relocation of measurement setups. Ergonomic considerations include non-slip texturing on grip surfaces and luminescent scale markings, ensuring reliable operation in low-light conditions. The complete assembly undergoes rigorous environmental testing, maintaining consistent performance across temperature extremes from -20℃ to 60℃.

Key operational advantages include rapid
