The Leica NAK2 meets all the requirements of precision levelling. As soon as it is set-up on a tripod and levelled with the bubble, the automatic compensator ensures that the line of sight is horizontal so that each staff reading is reliable.

• Clear objective aperture: 45 mm
• Field of view at 100 m: 2.2 m
• Shortest focusing distance: 1.6 m
• Multiplication factor: 100
• Additive constant: 0
• Working range of compensator: ~30’
• Setting accuracy of compensator (stand. dev.): 0.3"
• Sensitivity of circular level: 8'/2 mm
• Glass circle (K version): 400 gon (360°)
• Graduation diameter: 70 mm
• Graduation interval: 1 gon (1°)
• Reading by estimation to: 10 mgon (1’)
• Water- and dust resistance: IP53
• Temperature range:
• Operation –20°C to +50°C (– 4°F to 122°F)
• Storage –40°C to +70°C (–40°F to 158°F)

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 NAK2 the ideal precise level for deformation studies or industrial measuring tasks.

The NAK2 level 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.
