Product Overview
The Leica NA720 automatic level is a high-performance optical instrument designed for general construction surveys, road/railway profiling, and pipeline/tunnel elevation measurements. Featuring a 20x magnification telescope with premium multi-coated optics, it delivers sharp imaging even in low-light conditions at dawn, dusk, or shaded areas. The integrated compensator automatically levels within ±15 tilt range, significantly improving workflow efficiency. Its ergonomic design includes bilateral endless drives for fast targeting and 50cm short-distance measurement capability ideal for confined spaces.1610
Key Features
Renowned for ruggedness, the NA720 achieves IP57 protection against water/dust ingress and withstands accidental drops or mechanical vibrations without requiring recalibration. The optical system employs anti-glare coated lenses with erect image technology to minimize eye strain. Weighing only 1.6kg with compact dimensions (160×140mm), it balances portability with stability for extended field use. The nitrogen-filled telescope prevents internal fogging in humid environments.21217
Technical Specifications
This instrument provides 2.5mm elevation accuracy per km double-run, with 30mm objective lens diameter and 1°20´ field of view. Operating temperature ranges from -20℃ to +50℃, while storage tolerance extends to -40℃ to +70℃. The circular bubble offers 8 /2mm sensitivity, assisted by a coarse sighting notch for rapid object location. The 100x stadia ratio simplifies distance measurements.61619
Applications
Ideal for building settlement monitoring, municipal elevation control, and hydraulic structure inspections. Its reliability shines in projects like storage tank installations and bridge deformation surveys, minimizing weather-related downtime. The intuitive interface allows beginners to master basic operations quickly, making it a versatile tool for survey crews.42125
