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. |
- Graduations at 1cm
- 2m length and 4.3kg
- Body of the invar staff made of rigid aluminium profile with anodised surface;
- Yellow lacquered graduation side; print protected by polyester coating (1 mm thick);
- Invar tape seated in a protection groove of staff profile and tensioned by soft spring to compensate extension coefficient of staff profile. Extension coefficient: < 1.5 x 10-6;
- Foot plate slightly protrudes from staff body;
- Foot plate of chrome-alloy, chemically nickel-plated steel; hardened and ground;
- Equipped with circular bubble and fold-away handles as a standard. Handles zinced and powder-coated.
