Large Monitoring Prism
The Trimble Large Monitoring Prism is a high-precision reflective prism designed for use with optical total stations in geospatial and structural monitoring applications. Its larger prism diameter provides enhanced visibility and range, making it ideal for long-distance measurements, deformation monitoring, and construction survey points.
The prism ensures consistent reflective performance and supports both vertical and horizontal mounting, allowing flexible deployment on monitoring targets, structural points, or temporary benchmarks. Its calibrated prism constant ensures accurate distance measurements when used with Trimble or compatible total station systems.
The Trimble Large Monitoring Prism provides a robust, accurate, and versatile solution for optical surveying and monitoring, delivering high-quality data for engineers and surveyors in geotechnical and civil engineering projects.
