DIGITAL LEVELS

LEICA NA2002 & NA3003

Leica digital levels - innovative technology offering 50% greater productivity A single touch sets the digital level to measure, display and record Quick, reliable and precise Leica Geosystems led the digital level innovation with the first patented digital level in 1990. Since then, significant performance improvements assure surveyors and engineers achieve optimum productivity. Digital image processing permits height and distance information to be recorded electronically avoiding errors caused by manual recording and automating data processing. Field tests have shown that productivity savings of up to 50% can be gained with digital levelling. Many benefits support various survey levelling procedures. new feature that allows the data to be downloaded directly with a lemo0/RS232 cable. one touch auto-measure and record. single measurements or averaged repeat measurements automatic calculations of heights and misclosures setting of tolerances with auto-stop when tolerance is achieved height stake-out recording to removable storage option to dump stored data direct to computer measurements can be transferred on-line to a computer user guided check and adjust LevelPak software      NA2002      NA3003 Accuracy GKNL4-1.5mm GPCL2/3 - 0.9mm GKNL4-1.2mm GPCL2/3 - 0.4mm Magnification 24x Distance GKNL4 - 1.8m to 100m GPCL2/3  - 1.8m to 60m (1cm -5cm) tape accuracy Staff reading 1mm/0.1mm 0.1mm/0.01mm Measuring time 4s The NA3003 is optimised to provide top accuracy 0.4mm (1km double run levelling) with an invar staff.The measuring times can be lengthened to increase accuracy even further. Optional levelling procedures are included. The NA2002 provides survey accuracy for most survey and engineering tasks. The fibreglass staff is sufficient for such work however for increased accuracy an invar staff should be used. Every new NA2002 and NA3003 will be delivered with the levelling software LEICA LevelPak. LEICA LevelPak is a Windows solution for managing level data, heights, and computing and adjusting level lines. << Back
