For use with all Precise Levels the precision invar levelling staffs, Nedo has set new standards in terms of accuracy and reliability. They are used for first-order levelling and on large-scale construction sites with stringent requirements.
The most severe irregular graduation errors of the invar precision levelling staffs are less than ± 0.005 mm. This is achieved by directly engraving the graduation into the lacquering with an interferometrically controlled laser beam. The attained accuracy and the edge sharpness are optimal. |
