Wild N III / N3

Wild N3 with build in plan-parallel micrometer 1940 to 1972

The Wild N3 Precision Level is an outstanding instrument for all first order leveling work. Designed originally for geodetic networks it has been adopted universally as the ideal level for the precise measurement required in dam deformation surveys, industrial installations, aircraft fuselage assemblies and vertical displacement determinations. The plane parallel plate micrometer is mounted in front of the objective lens as a built-in feature of the N3 and is available in metric and non-metric models, giving reliable and simple estimation to 0.01 mm and 0.0005 inch, respectively. The reticule has part of its-horizontal line in the form of two wedge-shaped lines, converging towards the center allowing the staff graduation to be split or straddled, depending on the circumstances and on which part of the cross-hair is used. Collimation errors are corrected by means of a rotation of the objective lens cover glass which enables an exceptionally sensitive, but simple, adjustment to be made. Interchangeable eyepieces provide the possibility of observing with either an inverted or an upright image.
