Tribrach AJ13 (D1)

Eliminate structural drift during critical angle measurements with the Tribrach AJ13 (D1). Purpose-built for demanding land surveying, deformation monitoring, and civil engineering projects, this tribrach forms a highly rigid foundation between your tripod and optical sensors. Its optimized torsional stiffness ensures that the high-speed rotational forces of automated total stations will not introduce alignment deflection or angular errors.

Notable Elements:

• Universal 3-Jaw Interface: Standard forced centering mount compatible with international surveying instrument brands.
• Ultra-Smooth Leveling: Fine-threaded footscrews provide micro-adjustments even under heavy instrument loads.
• Integrated Circular Vial: High-visibility bubble vial simplifies and accelerates baseline setup.
• Torsional Rigidity: Heavy die-cast aluminum frame eliminates structural flexing during rapid instrument rotation.
