Leica NA2 Automatic Level

Universal application:

Levelling of all types and all orders of accuracy
Precise levelling and settlement determinations on buildings
Routine heighting for the construction of roads, railways, pipelines, tunnels and so forth
Setting-out work and control measurements on the construction site
Area levelling of high accuracy
Tacheometric levelling with the K-version on flat terrain by combining stadia and angular measurements with height readings
Deformation measurement and monitoring of bridges
Easy to level up

The advantage of this instrument is that, as soon as the bubble is centred, the line of sight is horizontal for all pointings of the telescope. The observer is freed of the time-consuming centring procedure involved with the traditional tubular level, and can concentrate on the business of staff readings.

Robust and automatic

The compensator is essentially a pendulum with a prism (4). The suspension system comprises four flexed tapes (1) made of a special alloy to ensure faultless functioning even at extreme temperatures. The compensator, which is located between the focusing lens and the crosshair reticle, is pneumatically damped against mechanical vibration and is screened against magnetic fields.

Minimum maintenance

In the unlikely event that the compensator is damaged (and this can only happen as a result of extremely harsh treatment) it is replaced easily, being held only by three screws.

Push-button control â“ added security

With most automatics one taps the tripod or instrument to check if the compensator is functioning. Leica Geosystems offers a far more sophisticated solution. Pressing the button under the NA2 eyepiece gives the compensator a gentle tap, so that you see the staff image swing smoothly away and then float gently back to give the horizontal line of sight. This check, which takes less than a second, is technically perfect, as the pendulum itself is activated and swings through its full range. It is also immediately apparent if the bubble is not centered.
