Product Description
The Stonex A30 Auto Level is built for surveying and construction leveling tasks. Delivering 1.5 mm standard deviation over 1 km double-run leveling, it minimizes human error and ensures consistent results. Its advanced compensator has minimal thermal expansion, maintaining stability even under changing temperature conditions.
With 28x magnification, a 36 mm objective lens, and a wide 125 field of view, the A30 delivers clear, sharp imaging. It focuses as close as 0.3 m, making it versatile for short- and long-range work. A free-rotation horizontal circle allows flexible angle readings, while the built-in tilt sensor prevents operation outside the compensator range. Rugged with an IP66 rating, the A30 is dust- and waterproof.
