The grz122 prism is a professional-grade 360 Degree Reflective Prism engineered for reliable, all-around accuracy in total station surveying. Built in the traditional Swiss Style 360° design, the grz122 prism provides consistent reflection performance and seamless integration with total station instruments.
Each 360 Degree Reflective Prism consists of six precisely aligned mini prisms, bonded together to form a single, stable 360° assembly. This configuration ensures high measurement precision and optimal reflection across all directions. The grz122 prism offers a +23.1 mm Swiss constant and ±2.0 mm centering accuracy, making it ideal for demanding field applications.
Constructed without a central stainless-steel axis, this Swiss-Style 360 Degree Reflective Prism features a lightweight, balanced body for improved portability and setup speed. The GRZ122 model uses a tough nylon housing, while the GRZ122M model features a metal body for enhanced strength and durability.
The grz122 prism also includes a quick-release push-button connection, enabling efficient mounting and removal from prism poles or tribrach adapters, ensuring smooth operation on every survey task.
