Automatic Construction Level 32x, IP56 and 1.6 mm per km Double Run - Leica NA532

Handover surveys need both a confident staff reading and an instrument that can stay out on site. The NA532 automatic level from Leica Geosystems reaches a standard deviation of 1.6 mm per kilometre double run to ISO 17123-2, works at 32x magnification and is rated IP56 against dust and powerful water jets. The compensator holds the line of sight horizontal by itself within ±15 arc minutes.

Benefits

• 1.6 mm per kilometre double run, the tightest figure in the NA500 series and a basis for handover, control and basic settlement monitoring.
• 32x magnification on a 36 mm objective aperture, the staff graduation stays readable over long sights and through shimmering air.
• IP56 rating, dust tight and protected against powerful water jets, plus an operating range of -20 °C to +50 °C.
• Compensator with a ±15 arc minute working range and setting accuracy better than 0.5 arc seconds, short settling time after vibration.
• Shortest target distance below 1.0 m and multiplication factor 100, height and distance come from the same reading.

Technical data

Applications

Handover and control surveys on floor slabs, screed and machine foundations. Precision levelling in civil engineering. Basic settlement monitoring on structures. Long levelling runs in road and track construction, where long sights cut the number of setups. Fall checks in drainage and sewer work.

Compatibility and scope of delivery

The NA532 mounts on common construction and survey tripods via the 5/8 inch thread and works with standard levelling staffs. For full accuracy a checked staff with centimetre or millimetre graduation is recommended. The delivery consists of the NA532 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.
