Universal Single Tilt Prism 64mm with Brass Knob and ABS Housing for Land Surveying and Tunnel Inspection Description A precision single tilt prism designed for reliable distance and angle measurements in surveying and inspection tasks. The 64mm optical prism, brass adjustment knob, and impactresistant ABS housing deliver accurate, repeatable returns while remaining simple to set up and operate. Key benefits Improved measurement accuracy: The single tilt design reduces angular errors when the prism is not vertical, helping maintain reliable returns. Smooth, precise adjustment: Brass knob provides fine, corrosionresistant control for centering and tilting the prism without slipping. Durable, lightweight housing: ABS outer casing protects the prism from impact and handling while keeping weight low for field portability. Versatile compatibility: Works with standard total stations, theodolites, and prism poles via common adapters and tribrachs. Faster field workflow: Simple mounting and adjustment cut setup time during surveys and inspections, reducing the need for repeat measurements. Features and attributes Function: Single tilt reflective prism for use as a target in optical distance and angle measurement instruments. Size: 64mm prism diameter for strong signal returns and clear target identification. Materials: Opticalgrade prism glass, brass adjustment knob, ABS housing for durability and low weight. Performance: Stable optical returns and repeatable alignment when used with compatible surveying instruments. Mounting: Designed for standard tripod and pole mounting interfaces used in land surveying and tunnel inspection. Practical applications Tunnel inspection: Verify alignment, monitor deformation, and check asbuilt positions during construction or routine inspection runs by establishing reliable prism targets along tunnel sections. Land surveying and topographic control: Set up as a reflector target for total stations during boundary surveys, topographic mapping, and stakeout tasks where precise positioning is required. Construction and engineering monitoring: Use for site control points, machine guidance checks, and deformation monitoring of structures where robust, repeatable prism readings are . What makes it stand out Combines a precision optical element with a corrosionresistant adjustment knob and a protective ABS housing for fieldready performance. Balanced design between durability and portability, suitable for repeated use in demanding environments such as tunnels and construction sites. Straightforward compatibility with common surveying instrument mounts simplifies integration into existing workflows. Use and care notes Mount securely on a stable pole or tribrach before taking measurements. Keep the prism surface clean and of dust or moisture for returns. Store in a protective case when not in use to avoid impact damage to the optical surface. Compatibility Compatible with standard total stations, theodolites, and prism poles that accept single tilt prism targets and common tripod or tribrach adapters.
