GPR121 All Metal Reflector Prism 0MM Constant for Total Station Surveying with Zero Offset Measurement

GPR121 All Metal Reflector Prism for Total Stations Measure Constant 0MM Survey Accessories Topography Key benefits Direct, consistent distance readings thanks to a measure constant of 0MM, simplifying calculations and reducing the need for prism offset corrections. Robust all metal construction delivers long service life in field conditions and resists deformation from routine handling. Simple alignment and stable mounting reduce setup time and help maintain measurement repeatability during surveys. What this product does Provides a precision reflective target for use with total stations and other electronic distance measurement instruments. Reflects instrument signals with a defined prism constant of 0MM so measured distances correspond directly to the prism face without additional correction. Why you need it Eliminates routine prism offset adjustments when recording reflector distances, streamlining workflow and minimizing potential for calculation errors. Durable metal housing protects the optical element, lowering the risk of damage and downtime in active surveying environments. Designed to be a reliable accessory for field crews who require consistent performance across repeated measurements. Key attributes Model: GPR121 Function: Reflector prism for distance measurement with total stations Measure constant: 0MM Material: All metal housing for durability Size and form: Compact, field friendly design for easy transport and mounting Performance: Stable reflectivity and repeatable results for topography and surveying tasks Compatibility Intended for use with total stations and EDM instruments that accept standard prism reflectors. Fits common prism holders, poles, and tripod mounting solutions used in surveying setups. Practical use scenarios Topographic surveying: Use the GPR121 as a target for capturing terrain elevation and contour data during site mapping. Construction layout and site control: Place the reflector at control points to record precise distances for alignment and layout checks. Boundary and cadastral surveys: Employ the prism for repeatable measurements when establishing property lines and control networks. Additional practical notes The 0MM prism constant makes this reflector a good choice when you want direct distance readings without additional prism constant compensation. The all metal housing is suitable for frequent field use and transport in tool bags or instrument cases. For results, pair with a stable prism mount or pole and ensure the prism face is clean and of obstructions before measuring. This GPR121 reflector prism is a straightforward accessory for survey professionals who need a durable, easy to use reflector with a zero prism constant for direct measurement workflows.
