Leica NAK2 Automatic Level

 

Leica NAK2 Automatic Level Product Information

The Leica NA2 universal automatic level meets all requirements regarding precision, convenience and reliability. It was designed by surveyors and development engineers with years of experience who know what a field instrument has to be able to do.

The NA2 soon pays for itself, because it can be used for all types of surveying jobs;

• On building sites for routine levelling
• In engineering projects
• For geodetic control at all levels of accuracy

With a compensator setting accuracy (stand. dev.) of 0.3” and a micrometer reading to 0.1 mm direct and 0.01 mm by estimation, the NA2 with GPM3 is an ideal combination for precise levelling and settlement determinations on buildings, deformation measurements and monitoring of bridges. Simply the NA2 with GPM3 can be used for all types of surveying job.

The NAK2 model has an internal glass circle for reading horizontal angles. Combined with the stadia calculation of distances from staff readings the NAK2 circle adds the application benefit of detail survey work.

• Push button compensator check
• Endless horizontal drive for left and right handed users
• Coarse and fine focusing knob
• Play-free footscrews
• Optional eyepieces available
• Top-class optics
