Leica NAK2 400 GON - Universal Automatic Level

The most accurate optical levels on site

Flexibility that pays off

The NA series is designed to be used for all types of surveying tasks. Independent if you have to do routine levelling on construction sites, check or monitor buildings, railways or roads, with the Leica NA levels you always have the right tool at hand.

Highest accuracy and reliability

Get reliable and precise levelling results even on sunny days. The top-class optical quality of Leica Geosystems always delivers a high contrast image and makes the read-out precise and easy even in unfavourable light conditions. Due to the high temperature stability the Leica NA levels deliver always reliable results and are relatively insensitive to direct solar radiation.

Fast and convenient set-up

Increase your efficiency and safe time with the fast to set-up Leica NA levels. Use the coarse movement of the focusing knob for rapid setting with minimum turning. The fine movement gives the final touch for a perfect image. To check if the compensator is functioning, simply press the button. This check will take less than a second and gives you a high level of security!

Universal application:

• Leveling of all types and all orders of accuracy
• Precise leveling and settlement determinations on buildings
• Routine heighting for the construction of roads, railways, pipelines, tunnels, and more
• Setting-out work and control measurements on the construction site
• Area leveling of high accuracy
• Tacheometric leveling with the K-version on flat terrain by combining stadia and angular measurements with height readings
• Deformation measurement and monitoring of bridges

Quickly set up, simple to use

Strong tripods

In principle, the NA2 can be set up on any Leica Geosystems tripod. In practice, for all-round purposes, we recommend the heavy-duty GST20 telescopic-leg tripod. For precise levelling the GST40 fixed-leg tripod is suitable because of its extreme rigidity

The modular relationship between instrument and tripod is an advantage when transport space is limited.

Centering is easy

The circular level only needs to be centered approximately to bring the compensator well into its working range of ~30', and so setting-up goes quicker.

The bubble is viewed positively via a pentaprism and is monitored down the eyepiece.

Play-free foot screws

The pitch of the smooth-running and backlash-free footscrews is such that the bubble can be centred in a very short time.

Independent of temperature

Unlike the tubular level of a traditional instrument, the NA2 universal automatic level is relatively insensitive to direct solar radiation and an umbrella need only be considered for the most precise levelling.
