Nedo precision Invar leveling rods are used for first-order leveling and for challenging work on large scale construction sites, for example, tunnels, roads, dams or power plants. The graduation of the precision Invar leveling rods is engraved in the paint coating with an interferometrically controlled laser beam, ensuring superior graduation accuracy and edge sharpness. Random graduation errors are less than + 0.015 mm. Nedo precision Invar leveling rods outperform the requirements of DIN 18717 / ISO 12858-1 and set standards in terms of accuracy.
