Wild Heerbrugg NK2 with rotatable telescope was made from 1936 to 1968. The Wild N2 engineers’ level is a strongly built, accurate and reliable general purpose instrument, which is easy to operate. It is unsurpassed for use on civil and constructional engineering projects, bench mark Establishment breaking down primary level networks, profiles, cross-sections, road and railway surveys and for photogrammetric height control. When fitted with a glass circle in the NK2 model it can be used in flat terrain for setting out works and for measuring horizontal angles and distances. Fine pointing is made with a horizontal clamp and a tangent screw and an accurate coincidence setting of the tubular level split bubble image is made by means of a tilting screw. The telescope and tubular level can rotate simultaneously about the longitudinal axis, enabling the vertical collimation to be checked easily at one instrumental set-up.
