Levelling set 20x magnification with aluminium tripod and 5 m staff - Leica NA520

Setting out heights rarely costs time at the instrument, it costs time collecting a tripod and a staff that match. This set removes that step by combining the Leica NA520 automatic level at 20x magnification, the GST103 aluminium tripod and the 5 metre CLR102 telescopic staff in one package. The standard deviation is 2.5 mm per kilometre of double run levelling to ISO 17123-2.

Benefits

• 20x magnification with an erect image, the staff graduation stays readable at normal site distances without mental gymnastics.
• 2.5 mm standard deviation per kilometre of double run levelling, accurate enough for excavation, foundations, drainage and height transfer in shell construction.
• Compensator with a plus/minus 15 arc minute working range and 0.5 arc second setting accuracy, the line of sight stays horizontal even when the ground under the tripod moves slightly.
• Shortest target distance of 1.0 m, so tight excavations, shafts and interiors can still be measured.
• IP56 protection to IEC 60529, dust and jetting water do not stop the work.
• Tripod and staff are included, the GST103 runs from 1.05 to 1.68 m and the CLR102 reads to 5 m before collapsing to transport length.

Technical data

Applications

Height transfer in shell construction, excavation and foundation checks, laying drainage runs to a fall, formwork and screed control, external works, terraces and path building, plus training and teaching in surveying.

Scope of delivery

• 1 x Leica NA520 automatic level with 360 degree circle, material number 840384
• 1 x Leica GST103 aluminium tripod with carrying strap, material number 726833
• 1 x Leica CLR102 telescopic staff, 5 m, 4 sections, material number 727588

Compatibility and scope of delivery

The level uses the standard 5/8 inch thread and therefore fits any tripod of that norm, including ball head tripods. The telescopic staff can be swapped for any other levelling staff with E graduation. No batteries are required, the instrument works purely optically and mechanically.
