Features 【Precision Measurement】 This total station prism features a +28.1mm constant, ensuring accurate offset correction for high-precision measurements. With an effective diameter of 25.4mm, it is for surveying prism applications in tunnels, railroads, and highways, delivering results in demanding environments. 【Enhanced Reflectivity】 The reflective prism for total station is coated with a high-performance reflective layer, maximizing the captures and redirection of the measurement beam. This minimizes sig nal loss, making it ideal for high accuracy prism tasks in mines and steep slopes. 【 Construction】 Built with K9 glass prism technology, this prism offers superior light transmission for clearer measurements. Its rugged ABS housing ensures durability, making it a dependable choice for rugged surveying equipment in dam inspections and subways projects. 【Versatile Design】 The 360 degree prism is designed with 6 integrated prisms, allowing measurements from any angle without repositioning. This flexibility is essential for prism for tunnels and mines, where dynamic and efficient surveying is required. 【Wide Compatibility】 This prism for Sokkia and trimbles is compatible with leading surveying instruments, making it a versatile tool for prism for dam and highway inspection. Its wide application range ensures it meets the needs of professionals in various industries. 1. +28.1mm Constant: This 360° prism has a constant of +28.1mm, which indicates the offset or correction value to be applied during the measurement. It also has an effective diameter of 25.4mm, which determines the size of the measurement area. These specifications make the prism suitable for a variety of applications that require accurate measurements. 2. Reflective Coating: This total station reflector prism features a reflective coating that ensures a higher percentage of the measurement beam is captured and redirected to minimize loss and maximize accuracy. 3. Sturdy And Rugged: This 360 degree mini prism is made of excellent quality K9 glass, known for its high light transmission properties, which means it allows a high percentage of the measurement beam to pass through, resulting in clearer, more accurate measurements. 4. Good Performance: This 360° total station prism design has 6 separate prisms joined together to allow the measurement beam to reflect from any angle. This design feature provides flexibility and convenience during the measurement process as it allows reflection from all directions without the need to reposition the prisms. 5. Wide Application: This 360 degree reflective prism has a wide range of applications and can be used in inspection scenarios such as tunnels, railroads, dams, mines, highways, steep slopes, etc. for efficient and measurements. Specification: Item Type: 360° Prism Material: K9 Glass, ABS Constant: +28.1mm Deviation: 3 Arc Seconds Effective Diameter: Approx. 25.4mm / 1in Application: Tunnel, subways, Mine, Highway and other Inspection, Applicable to for Sokkia, for trimbles and Other Measuring Instruments.
