The AT-B series levels feature world-class auto-compensation, incorporating four low thermal expansion suspension wires. This gives you a stabilized line of sight for perfect measurements when working on busy sites or near heavy machinery.

An IPX6 rating ensures that the AT-B is tested to withstand sudden showers or torrential rainfall. The advanced protection design also prevents clouding or condensation inside the telescope.



Super quick leveling with stabilized line of sight

Thanks to the finely tuned autocollimation system, the AT-B series of auto levels is ideal for determining height differentials on busy and noisy job sites. With a small and lightweight design, they have excellent horizontal circle visibility, superior gear ratios for shock and vibration, and improved tangents and knobs.
