Leica NA2 / NAK2 Automatic Levels

Model: Leica NA2 / NAK2 Category: Auto Levels
Precision Levels for all your stringent requirements.

Leica NA2 and Leica NAK2 are two universal automatic levels meet all the requirements of precision levelling.

Angle measurement with the NAK2

The model NAK2 has an internal glass circle which is read via a scale microscope and which can be set to any value by turning the rim around the base of the instrument. Tacheometric levelling is also available with the K-version on fl at terrain by combining stadia and angular measurements with height readings.

  • Standard deviation per km: 0.7mm (double-run levelling). Protection: IP53. Operating temperature: -20 °C to +50 °C. Weight: 2kg.
  • Telescope – Magnifi cation: 32x. Clear objective aperture: 45mm. Shortest focusing distance: 1.6m, Multiplication factor: 100. Additive constant: 0.
  • Compensator – Working range: ± 30’. Setting accuracy (stand. dev.): 0.3”. Sensitivity of circular level: 10/2mm. Graduation interval of Hz: 1 °.
Leica’s top-class optical quality gives the NA2 & NAK2 a bright high contrast image.

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
