Automatic Construction Level 24x, IP56 and 1.9 mm per km Double Run - Leica NA524

Accuracy is of little use if the instrument cannot take the working day on site. The NA524 automatic level from Leica Geosystems delivers both, a standard deviation of 1.9 mm per kilometre double run to ISO 17123-2 and a housing rated IP56, dust tight and protected against powerful water jets. The 24x magnification keeps the staff sharp over longer sights, the compensator works within a range of ±15 arc minutes.

Benefits

• 1.9 mm per kilometre double run, clearly tighter than the 2.5 mm of the entry class and therefore usable for control surveys on floor slabs and screed.
• 24x magnification on a 36 mm objective aperture, longer sights per setup and fewer instrument moves on long runs.
• IP56 rating, dust tight and protected against powerful water jets, the instrument stays usable in rain and during hose down.
• Operating range of -20 °C to +50 °C, enough headroom for summer work on asphalt and in heated up halls.
• Compensator setting accuracy better than 0.5 arc seconds and a short settling time after vibration at the tripod.

Technical data

Applications

Height control on foundations, floor slabs and screed. Levelling runs over longer distances in civil engineering and road construction. Fall checks in drainage and sewer work. Earthworks with longitudinal and cross sections. Sites with heavy dust and moisture where equipment is cleaned regularly.

Compatibility and scope of delivery

The NA524 mounts on common construction and survey tripods via the 5/8 inch thread and works with standard levelling staffs. The delivery consists of the NA524 automatic level, the carrying case, the user manual on CD in 29 languages, an Allen key, a bent pick, the customer information and a Protect card. Tripod and levelling staff are not included.
