Automatic Construction Level 32x, 1.8 mm per km Double Run - Leica NA332

Where levels have to hold to a few millimetres, staff readability decides the result. The NA332 automatic level from Leica Geosystems supplies 32x magnification on a 36 mm objective aperture and reaches a standard deviation of 1.8 mm per kilometre double run to ISO 17123-2. The air damped compensator holds the line of sight horizontal within ±15 arc minutes at a setting accuracy better than 0.5 arc seconds.

Benefits

• 1.8 mm per kilometre double run, the tightest figure in the NA300 series and a sound basis for control and handover surveys.
• 32x magnification, the staff graduation stays readable over long sights and through shimmering air, which cuts estimation error when interpolating.
• Compensator setting accuracy better than 0.5 arc seconds and a short settling time after the instrument is knocked.
• Shortest target distance below 1.0 m and multiplication factor 100, height and distance come from the same reading.
• IP54 protection to IEC 60529 and an operating range of -20 °C to +40 °C, the instrument stays usable on site instead of in the van.

Technical data

Applications

Precision levelling and handover surveys on floor slabs, screed and machine foundations. Checking falls in drainage and sewer construction. Settlement monitoring on structures. Long levelling runs in road and track construction where long sights shorten the run. Setting out via the 360 degree horizontal circle.

Compatibility and scope of delivery

The NA332 mounts on common construction and survey tripods via the 5/8 inch thread and works with standard levelling staffs. For full accuracy a calibrated staff with centimetre or millimetre graduation is recommended. The delivery consists of the NA332 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.
