A30 Auto Level (Stonex)

Stonex brings the benefits of Auto Level to construction applications at an affordable price with the reliable, easy-to-use A30 Auto Level. The Stonex A30 Auto Level minimizes human error and maximizes the ease of levelling work, allowing increased productivity and performance. In few seconds height difference and distance can be measured. A30 guarantees high accuracy with ±1.5mm standard deviation of 1km round-trip leveling measurement. The compensator of the Stonex A30 has minimal thermal expansion coefficient, providing unmatched durability and accuracy. Error reducing functions, such as the tilt sensor prevent the system from measuring if the user operates outside the compensator range. Multiple reading for horizontal angles available ( 1° or 1gon ). Any angle can be read thanks to the free rotation characteristics. The Stonex A30 Auto Level is the perfect instrument for your daily levelling tasks.
