Automatic Level Leica NA2/NAK2

Leica NA2 and Leica NAK2 are two universal automatic levels meet all the requirements of precision levelling. Leica' s top-class optical quality gives the NA2 & NAK2 a bright high contrast image. * push button compensator check * endless horizontal drive for left and right handed users * coarse and fine focusing knob * play-free footscrews * optional eyepieces available * top-class optics * Per 1km double run To improve accuracy a parallel plate micrometer can be fitted over the telescope objective. The parallel plate micrometer permits direct readings to 0.1mm and estimated readings to 0.01mm. This makes the NA2 and NAK2 an ideal precise level for deformation studies or industrial measuring tasks. The NAK2 model has an internal glass circle for reading horizontal angles. Combined with the stadia calculation of distances from staff readings the NAK2 circle adds the application benefit of detail survey work.
