The Topcon AT-B Series Automatic Levels deliver precision, durability, and reliability for demanding construction and drainage jobsites. Engineered for contractors who need consistent accuracy in the field, these rugged automatic levels combine advanced optical technology with construction-grade durability to handle the toughest project conditions.
Available in three magnification options—32x, 28x, and 24x—the AT-B Series provides contractors with flexibility to match their specific measurement needs. Higher magnification models excel for long-distance sightings and detailed elevation work, while lower magnification options improve field of view and ease of use in tight spaces. This versatility makes the AT-B Series ideal for everything from foundation leveling and grade establishment to drainage system layout and concrete finishing.
Jobsite accuracy is built into every detail. The magnetic damping system minimizes vibration and oscillation, allowing the internal compensator to settle quickly and precisely. This means faster readings, reduced setup time, and more reliable measurements throughout your workday. On active construction sites where equipment vibration from nearby machinery is common, magnetic damping makes a measurable difference in data quality and consistency.
The 20cm minimum focusing distance is a game-changer for contractors working in confined spaces, tight building interiors, or complex site conditions. Unlike conventional levels requiring longer minimum distances, the AT-B Series lets you take accurate shots in challenging locations where space is limited—whether you're checking grades inside building foundations, working near walls, or establishing elevations in cramped utility trenches.
Built to withstand harsh jobsite environments, the AT-B Series features IPX6 water resistance, protecting internal optics from dust, spray, and moisture common on active construction sites. The rugged design handles the bumps and impacts of daily field use, while the optical quality remains constant through countless projects.
Contractors trust Topcon automatic levels for consistent accuracy that directly impacts project success. Whether you're managing single-family residential grading, commercial site development, or drainage infrastructure, the AT-B Series delivers the precision measurements that keep projects on grade and on schedule. The combination of reliable automatic compensation, fast setup, and durable construction makes these levels a smart investment for any contractor serious about jobsite accuracy and efficiency.
