Key Features 

 

1. Optical Plummet Centering—The built-in optical plummet provides precise vertical alignment over a ground point with centering accuracy under 0.5mm, eliminating guesswork during instrument setup.

2. Quick-Release Adaptor System—The push-button quick-release mechanism allows users to swap instruments in seconds without disturbing the tribrach’s leveled position, saving time on multi-point setups.

3. Universal Brand Compatibility—The 5/8″ × 11 UNC thread and dedicated adaptor plate ensure compatibility with Leica, Topcon, Sokkia, South, Hi-Target, and other popular total station brands used in Bangladesh.

4. Durable Aluminum Alloy Body—The die-cast aluminum alloy construction resists corrosion and mechanical stress, maintaining structural rigidity even during long fieldwork sessions in Bangladesh’s humid climate.

5. High-Sensitivity Bubble Level—The circular bubble level with 8′ / 2mm sensitivity delivers fast coarse leveling, while the plate level enables fine adjustment for precise instrument orientation.

6. Smooth Three-Screw Adjustment—Three precision foot screws provide balanced, drag-free leveling motion, allowing surveyors to achieve stable horizontal alignment quickly on uneven or soft ground surfaces.

Frequently Asked Questions(FAQ)

Q1: What is a tribrach with adaptor used for in surveying? A tribrach with adaptor serves as the leveling base that connects a surveying instrument — such as a total station, theodolite, or GPS receiver — to a tripod. The tribrach levels the instrument horizontally over a ground point, and the adaptor allows the user to detach and reattach the instrument quickly without disturbing the level and centering Tribrach with Adaptor .

Q2: Does this tribrach fit Leica, Topcon, and South total stations? Yes. The tribrach with adaptor from ASTZBD uses the universal 5/8″ × 11 UNC thread interface. The included adaptor plate fits Leica, Topcon, Sokkia, South, Hi-Target, and most other major total station brands available in the Bangladesh market.

Q3: What is the centering accuracy of the optical plummet? The optical plummet on this tribrach achieves a centering accuracy of ≤0.5mm at a standard instrument height of 1.5m. This level of accuracy meets the requirements for precision cadastral, engineering, and control surveys.

Q4: Can I use this tribrach with a GPS or GNSS receiver? Yes. GPS and GNSS receivers use the same standard 5/8″ × 11 thread for tripod mounting. The adaptor accepts GPS receiver bases from Hi-Target, South, Trimble, and other brands. This makes the tribrach with adaptor a versatile tool for both optical and satellite-based surveying.
