A level rarely fails on site because of its optics, it fails because of water, dust and fogged lenses. The NA720 automatic level from Leica Geosystems answers that with an IP57 rating, dust tight and protected against temporary immersion, plus a nitrogen filled telescope that does not fog internally. The standard deviation is 2.5 mm per kilometre double run, at a 30 m sight it is 1.5 mm for a single measurement.
Benefits
- IP57 rating, dust tight and protected against temporary immersion, the instrument keeps working after a drop into a wet excavation.
- Nitrogen filled telescope, no internal fogging when the instrument moves between van, hall and open air.
- Shortest target distance of 0.5 m, considerably closer than the usual 1.0 m, so shafts and tight interiors can still be measured.
- Double sided endless fine drive, the target is approached from either side without hunting for an end stop.
- Compensator with a ±15 arc minute working range and setting accuracy better than 0.5 arc seconds.
- Horizontal circle readable in 360 degrees or 400 gon, matching whichever unit the drawings use.
