The AdirPro 2.5-inch Monitoring Prism Base Kit provides high performance, accuracy and easy to calculate offsets for numerous surveying tasks. Ideal for surveyors, contractors, engineers, and architects.
It calculates short-range angles and distance measurements with incredible precision. You can easily adjust the surveying prism in X and Y axis to obtain exact measurements. It easily installs on buildings, railroad tracks, bridge piers and other structures. Its robust and durable design is made of aluminum and is guaranteed to last for many years.
Surveying prisms and holders that are not in the nodal position can cause angular errors when using the prism apex as a target, especially when it’s not perfectly pointed towards the measuring instrument. The AdirPro Monitoring Prism Base Kit features a nodal prism that reduces pointing errors with its nodal point alignment at -41mm offset for 2.5-inch prism. It effectively minimizes the error associated with misalignments. This offset also provides the optimal angle suitable for land and area surveying. This heavy duty prism base kit also includes an anchor bolt for additional security.
