Operating Temperature: -4°F to +122°F (-20°C to +50°C) 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 1°25′ 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.
