Precision optical reflector with 0mm constant — compatible with total stations and GPR1 / GPH1 systems Key benefits Eliminates calculation errors: Calibrated to a 0mm constant so measurements require no additional offsets, reducing setup time and simplifying post‑processing. Plugandplay compatibility: Directly compatible with total stations and GPR1 and GPH1 systems for reliable integration into existing survey workflows. Longrange, clarity returns: Precisioncut optical glass and a polished surface deliver clear reflections for accurate measurements up to 800 meters. Durable field performance: Robust housing protects optical components and preserves alignment under rough handling and harsh site conditions. Reliable in variable lighting: Enhanced reflectivity maintains strong signals in bright, low, or mixed lighting to keep data consistent. Features and function 0mm constant: Factory calibrated so survey readings do not require compensating calculations, simplifying data collection and reducing human error. Optical glass lens precision: quality, precisioncut optical glass provides low distortion and reflectivity for accurate distance and angle measurement within an 800 m range. Sturdy construction: Tough housing protects internal optics from impact, dust, and moisture while preserving optical alignment over repeated field use. Enhanced reflectivity: Optimized glass and surface finish increase signal strength and clarity, improving measurement reliability at long distances and in challenging lighting. Practical applications Land surveying: Use with total stations and GPR1 / GPH1 systems for boundary surveys, control point setup, and precision stakeout where consistent, error measurements are required. Construction layout and engineering: Ideal for site layout, alignment checks, and structural surveys on demanding construction sites where durability and quick data processing save time. Topographic and longrange surveys: Effective for corridor mapping, road and bridge projects, and other topographic work requiring reliable returns up to 800 meters. Why professionals choose this reflector Reduces field and office workload by removing constant offsets from workflows. Integrates seamlessly with total stations and GPR1 / GPH1 equipment used by surveyors and engineers. Built to withstand realworld site conditions while preserving the optical performance needed for accurate, repeatable measurements.
