Innovations help you work in all conditions
Incorporating four low thermal expansion suspension wires, the AT-B series levels feature world class auto-compensation, allowing a stabilized line of sight for perfect measurements when working on busy sites or near heavy machinery.
The IPx6 rating ensures that the AT-B is protected against powerful water jets from all directions, meaning that it withstands sudden showers or torrential rainfall. The advanced protection design also deters clouding or condensation inside the telescope.
