Automatic Construction Level 24x, 2.0 mm per km Double Run - Leica NA324

The longer the sighting distance, the fewer setups a levelling run needs, but only as long as the staff stays sharp. The NA324 automatic level from Leica Geosystems solves that with 24x magnification on a 36 mm objective aperture and reaches a standard deviation of 2.0 mm per kilometre double run to ISO 17123-2. The air damped compensator levels the line of sight by itself within ±15 arc minutes.

Benefits

• 2.0 mm per kilometre double run, half a millimetre tighter than the NA320 and therefore usable for precision and control levelling in building work.
• 24x magnification, longer sights per setup and consequently fewer instrument moves on long runs.
• Compensator setting accuracy better than 0.5 arc seconds, the line of sight stays stable even when the tripod takes light vibration.
• Shortest target distance below 1.0 m from the instrument axis, so cramped setup positions remain usable.
• IP54 protection to IEC 60529, operating temperature from -20 °C to +40 °C, suitable for year round site use.

Technical data

Applications

Levelling runs over longer distances in civil engineering and road construction. Height control on foundations, floor slabs and screed where 2 mm per kilometre is required. Basic settlement monitoring on structures. Longitudinal and cross sections in earthworks. Setting out right angles via the horizontal circle.

Compatibility and scope of delivery

The NA324 mounts on common construction and survey tripods via the 5/8 inch thread and works with standard levelling staffs. The delivery consists of the NA324 automatic level, the carrying case, the user manual on CD in 29 languages, an Allen key, a bent pick and the customer information. Tripod and levelling staff are not included.
